Struct DateTime

pub struct DateTime { /* private fields */ }

GDateTime is a structure that combines a Gregorian date and time into a single structure.

GDateTime provides many conversion and methods to manipulate dates and times. Time precision is provided down to microseconds and the time can range (proleptically) from 0001-01-01 00:00:00 to 9999-12-31 23:59:59.999999. GDateTime follows POSIX time in the sense that it is oblivious to leap seconds.

GDateTime is an immutable object; once it has been created it cannot be modified further. All modifiers will create a new GDateTime. Nearly all such functions can fail due to the date or time going out of range, in which case None will be returned.

GDateTime is reference counted: the reference count is increased by calling GLib::DateTime::ref() and decreased by calling GLib::DateTime::unref(). When the reference count drops to 0, the resources allocated by the GDateTime structure are released.

Many parts of the API may produce non-obvious results. As an example, adding two months to January 31st will yield March 31st whereas adding one month and then one month again will yield either March 28th or March 29th. Also note that adding 24 hours is not always the same as adding one day (since days containing daylight savings time transitions are either 23 or 25 hours in length).

GLib type: Shared boxed type with reference counted clone semantics.

Implementations

impl DateTime

pub fn as_ptr(&self) -> *mut GDateTime

Return the inner pointer to the underlying C value.

pub unsafe fn from_glib_ptr_borrow(ptr: &*mut GDateTime) -> &Self

Borrows the underlying C value.

impl DateTime

pub fn new( tz: &TimeZone, year: i32, month: i32, day: i32, hour: i32, minute: i32, seconds: f64, ) -> Result<DateTime, BoolError>

Creates a new #GDateTime corresponding to the given date and time in the time zone @tz.

The @year must be between 1 and 9999, @month between 1 and 12 and @day between 1 and 28, 29, 30 or 31 depending on the month and the year.

@hour must be between 0 and 23 and @minute must be between 0 and 59.

@seconds must be at least 0.0 and must be strictly less than 60.0. It will be rounded down to the nearest microsecond.

If the given time is not representable in the given time zone (for example, 02:30 on March 14th 2010 in Toronto, due to daylight savings time) then the time will be rounded up to the nearest existing time (in this case, 03:00). If this matters to you then you should verify the return value for containing the same as the numbers you gave.

In the case that the given time is ambiguous in the given time zone (for example, 01:30 on November 7th 2010 in Toronto, due to daylight savings time) then the time falling within standard (ie: non-daylight) time is taken.

It not considered a programmer error for the values to this function to be out of range, but in the case that they are, the function will return None.

You should release the return value by calling g_date_time_unref() when you are done with it.

tz

a #GTimeZone

year

the year component of the date

month

the month component of the date

day

the day component of the date

hour

the hour component of the date

minute

Returns

a new #GDateTime, or None

pub fn from_iso8601( text: &str, default_tz: Option<&TimeZone>, ) -> Result<DateTime, BoolError>

Creates a #GDateTime corresponding to the given ISO 8601 formatted string @text. ISO 8601 strings of the form <date><sep><time><tz> are supported, with some extensions from RFC 3339 as mentioned below.

Note that as #GDateTime “is oblivious to leap seconds”, leap seconds information in an ISO-8601 string will be ignored, so a 23:59:60 time would be parsed as 23:59:59.

<sep> is the separator and can be either ‘T’, ‘t’ or ’ ’. The latter two separators are an extension from RFC 3339.

<date> is in the form:

• YYYY-MM-DD - Year/month/day, e.g. 2016-08-24.
• YYYYMMDD - Same as above without dividers.
• YYYY-DDD - Ordinal day where DDD is from 001 to 366, e.g. 2016-237.
• YYYYDDD - Same as above without dividers.
• YYYY-Www-D - Week day where ww is from 01 to 52 and D from 1-7, e.g. 2016-W34-3.
• YYYYWwwD - Same as above without dividers.

<time> is in the form:

• hh:mm:ss(.sss) - Hours, minutes, seconds (subseconds), e.g. 22:10:42.123.
• hhmmss(.sss) - Same as above without dividers.

<tz> is an optional timezone suffix of the form:

• Z - UTC.
• +hh:mm or -hh:mm - Offset from UTC in hours and minutes, e.g. +12:00.
• +hh or -hh - Offset from UTC in hours, e.g. +12.

If the timezone is not provided in @text it must be provided in @default_tz (this field is otherwise ignored).

This call can fail (returning None) if @text is not a valid ISO 8601 formatted string.

You should release the return value by calling g_date_time_unref() when you are done with it.

Returns

the difference between the two #GDateTime, as a time span expressed in microseconds.

pub fn format(&self, format: &str) -> Result<GString, BoolError>

Creates a newly allocated string representing the requested @format.

The format strings understood by this function are a subset of the strftime() format language as specified by C99. The D, U and W conversions are not supported, nor is the E modifier. The GNU extensions k, l, s and P are supported, however, as are the 0, _ and - modifiers. The Python extension f is also supported.

In contrast to strftime(), this function always produces a UTF-8 string, regardless of the current locale. Note that the rendering of many formats is locale-dependent and may not match the strftime() output exactly.

The following format specifiers are supported:

• a: the abbreviated weekday name according to the current locale
• A: the full weekday name according to the current locale
• b: the abbreviated month name according to the current locale
• B: the full month name according to the current locale
• c: the preferred date and time representation for the current locale
• C: the century number (year/100) as a 2-digit integer (00-99)
• d: the day of the month as a decimal number (range 01 to 31)
• e: the day of the month as a decimal number (range 1 to 31); single digits are preceded by a figure space (U+2007)
• F: equivalent to Y`-`m`-`d (the ISO 8601 date format)
• g: the last two digits of the ISO 8601 week-based year as a decimal number (00-99). This works well with V and u.
• G: the ISO 8601 week-based year as a decimal number. This works well with V and u.
• h: equivalent to b
• H: the hour as a decimal number using a 24-hour clock (range 00 to 23)
• I: the hour as a decimal number using a 12-hour clock (range 01 to 12)
• j: the day of the year as a decimal number (range 001 to 366)
• k: the hour (24-hour clock) as a decimal number (range 0 to 23); single digits are preceded by a figure space (U+2007)
• l: the hour (12-hour clock) as a decimal number (range 1 to 12); single digits are preceded by a figure space (U+2007)
• m: the month as a decimal number (range 01 to 12)
• M: the minute as a decimal number (range 00 to 59)
• f: the microsecond as a decimal number (range 000000 to 999999)
• p: either ‘AM’ or ‘PM’ according to the given time value, or the corresponding strings for the current locale. Noon is treated as ‘PM’ and midnight as ‘AM’. Use of this format specifier is discouraged, as many locales have no concept of AM/PM formatting. Use c or X instead.
• P: like p but lowercase: ‘am’ or ‘pm’ or a corresponding string for the current locale. Use of this format specifier is discouraged, as many locales have no concept of AM/PM formatting. Use c or X instead.
• r: the time in a.m. or p.m. notation. Use of this format specifier is discouraged, as many locales have no concept of AM/PM formatting. Use c or X instead.
• R: the time in 24-hour notation (H`:`M)
• s: the number of seconds since the Epoch, that is, since 1970-01-01 00:00:00 UTC
• S: the second as a decimal number (range 00 to 60)
• t: a tab character
• T: the time in 24-hour notation with seconds (H`:`M`:`S)
• u: the ISO 8601 standard day of the week as a decimal, range 1 to 7, Monday being 1. This works well with G and V.
• V: the ISO 8601 standard week number of the current year as a decimal number, range 01 to 53, where week 1 is the first week that has at least 4 days in the new year. See g_date_time_get_week_of_year(). This works well with G and u.
• w: the day of the week as a decimal, range 0 to 6, Sunday being 0. This is not the ISO 8601 standard format — use u instead.
• x: the preferred date representation for the current locale without the time
• X: the preferred time representation for the current locale without the date
• y: the year as a decimal number without the century
• Y: the year as a decimal number including the century
• z: the time zone as an offset from UTC (+hhmm)
• %:z: the time zone as an offset from UTC (+hh:mm). This is a gnulib strftime() extension. Since: 2.38
• %::z: the time zone as an offset from UTC (+hh:mm:ss). This is a gnulib strftime() extension. Since: 2.38
• %:::z: the time zone as an offset from UTC, with : to necessary precision (e.g., -04, +05:30). This is a gnulib strftime() extension. Since: 2.38
• Z: the time zone or name or abbreviation
• %%: a literal % character

Some conversion specifications can be modified by preceding the conversion specifier by one or more modifier characters.

The following modifiers are supported for many of the numeric conversions:

• O: Use alternative numeric symbols, if the current locale supports those.
• _: Pad a numeric result with spaces. This overrides the default padding for the specifier.
• -: Do not pad a numeric result. This overrides the default padding for the specifier.
• 0: Pad a numeric result with zeros. This overrides the default padding for the specifier.

The following modifiers are supported for many of the alphabetic conversions:

• ^: Use upper case if possible. This is a gnulib strftime() extension. Since: 2.80
• #: Use opposite case if possible. This is a gnulib strftime() extension. Since: 2.80

Additionally, when O is used with B, b, or h, it produces the alternative form of a month name. The alternative form should be used when the month name is used without a day number (e.g., standalone). It is required in some languages (Baltic, Slavic, Greek, and more) due to their grammatical rules. For other languages there is no difference. OB is a GNU and BSD strftime() extension expected to be added to the future POSIX specification, Ob and Oh are GNU strftime() extensions. Since: 2.56

Since GLib 2.80, when E is used with c, C, x, X, y or Y, the date is formatted using an alternate era representation specific to the locale. This is typically used for the Thai solar calendar or Japanese era names, for example.

• Ec: the preferred date and time representation for the current locale, using the alternate era representation
• EC: the name of the era
• Ex: the preferred date representation for the current locale without the time, using the alternate era representation
• EX: the preferred time representation for the current locale without the date, using the alternate era representation
• Ey: the year since the beginning of the era denoted by the EC specifier
• EY: the full alternative year representation

format

a valid UTF-8 string, containing the format for the #GDateTime

Returns

a newly allocated string formatted to the requested format or None in the case that there was an error (such as a format specifier not being supported in the current locale). The string should be freed with g_free().

pub fn format_iso8601(&self) -> Result<GString, BoolError>

Available on crate feature v2_62 only.

Since GLib 2.66, this will output to sub-second precision if needed.

Returns

a newly allocated string formatted in ISO 8601 format or None in the case that there was an error. The string should be freed with g_free().

pub fn day_of_month(&self) -> i32

Retrieves the day of the month represented by @self in the gregorian calendar.

Returns

the day of the month

pub fn day_of_week(&self) -> i32

Returns

the day of the week

pub fn day_of_year(&self) -> i32

Retrieves the day of the year represented by @self in the Gregorian calendar.

Returns

the day of the year

pub fn hour(&self) -> i32

Retrieves the hour of the day represented by @self

Returns

the hour of the day

pub fn microsecond(&self) -> i32

Retrieves the microsecond of the date represented by @self

Returns

the microsecond of the second

pub fn minute(&self) -> i32

Retrieves the minute of the hour represented by @self

Returns

pub fn month(&self) -> i32

Retrieves the month of the year represented by @self in the Gregorian calendar.

Returns

the month represented by @self

pub fn second(&self) -> i32

Retrieves the second of the minute represented by @self

Returns

the second represented by @self

pub fn seconds(&self) -> f64

Retrieves the number of seconds since the start of the last minute, including the fractional part.

Returns

the number of seconds

pub fn timezone(&self) -> TimeZone

Available on crate feature v2_58 only.

Get the time zone for this @self.

Returns

the time zone

pub fn timezone_abbreviation(&self) -> GString

Determines the time zone abbreviation to be used at the time and in the time zone of @self.

For example, in Toronto this is currently “EST” during the winter months and “EDT” during the summer months when daylight savings time is in effect.

Returns

the time zone abbreviation. The returned string is owned by the #GDateTime and it should not be modified or freed

pub fn utc_offset(&self) -> TimeSpan

Determines the offset to UTC in effect at the time and in the time zone of @self.

The offset is the number of microseconds that you add to UTC time to arrive at local time for the time zone (ie: negative numbers for time zones west of GMT, positive numbers for east).

If @self represents UTC time, then the offset is always zero.

Returns

the number of microseconds that should be added to UTC to get the local time

pub fn week_numbering_year(&self) -> i32

Returns the ISO 8601 week-numbering year in which the week containing @self falls.

This function, taken together with g_date_time_get_week_of_year() and g_date_time_get_day_of_week() can be used to determine the full ISO week date on which @self falls.

This is usually equal to the normal Gregorian year (as returned by g_date_time_get_year()), except as detailed below:

For Thursday, the week-numbering year is always equal to the usual calendar year. For other days, the number is such that every day within a complete week (Monday to Sunday) is contained within the same week-numbering year.

For Monday, Tuesday and Wednesday occurring near the end of the year, this may mean that the week-numbering year is one greater than the calendar year (so that these days have the same week-numbering year as the Thursday occurring early in the next year).

For Friday, Saturday and Sunday occurring near the start of the year, this may mean that the week-numbering year is one less than the calendar year (so that these days have the same week-numbering year as the Thursday occurring late in the previous year).

An equivalent description is that the week-numbering year is equal to the calendar year containing the majority of the days in the current week (Monday to Sunday).

Note that January 1 0001 in the proleptic Gregorian calendar is a Monday, so this function never returns 0.

Returns

the ISO 8601 week-numbering year for @self

pub fn week_of_year(&self) -> i32

Returns the ISO 8601 week number for the week containing @self. The ISO 8601 week number is the same for every day of the week (from Moday through Sunday). That can produce some unusual results (described below).

The first week of the year is week 1. This is the week that contains the first Thursday of the year. Equivalently, this is the first week that has more than 4 of its days falling within the calendar year.

The value 0 is never returned by this function. Days contained within a year but occurring before the first ISO 8601 week of that year are considered as being contained in the last week of the previous year. Similarly, the final days of a calendar year may be considered as being part of the first ISO 8601 week of the next year if 4 or more days of that week are contained within the new year.

Returns

the ISO 8601 week number for @self.

pub fn year(&self) -> i32

Retrieves the year represented by @self in the Gregorian calendar.

Returns

the year represented by @self

pub fn ymd(&self) -> (i32, i32, i32)

the return location for the month of the year, or None.

day

the return location for the day of the month, or None.

pub fn is_daylight_savings(&self) -> bool

Determines if daylight savings time is in effect at the time and in the time zone of @self.

Returns

true if daylight savings time is in effect

pub fn to_local(&self) -> Result<DateTime, BoolError>

Creates a new #GDateTime corresponding to the same instant in time as @self, but in the local time zone.

This call is equivalent to calling g_date_time_to_timezone() with the time zone returned by g_time_zone_new_local().

Returns

the newly created #GDateTime which should be freed with g_date_time_unref(), or None

pub fn to_timezone(&self, tz: &TimeZone) -> Result<DateTime, BoolError>

Create a new #GDateTime corresponding to the same instant in time as @self, but in the time zone @tz.

This call can fail in the case that the time goes out of bounds. For example, converting 0001-01-01 00:00:00 UTC to a time zone west of Greenwich will fail (due to the year 0 being out of range).

tz

the new #GTimeZone

Returns

the newly created #GDateTime which should be freed with g_date_time_unref(), or None

pub fn to_unix(&self) -> i64

Gives the Unix time corresponding to @self, rounding down to the nearest second.

Unix time is the number of seconds that have elapsed since 1970-01-01 00:00:00 UTC, regardless of the time zone associated with @self.

Returns

the Unix time corresponding to @self

pub fn to_unix_usec(&self) -> i64

Available on crate feature v2_80 only.

Feeds a slice of this type into the given Hasher.

impl Ord for DateTime

fn cmp(&self, other: &Self) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for DateTime

fn eq(&self, other: &Self) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl PartialOrd for DateTime

fn partial_cmp(&self, other: &Self) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &Rhs) -> bool

Tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Rhs) -> bool

Tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Rhs) -> bool

Tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool

Tests greater than or equal to (for self and other) and is used by the >= operator.

impl StaticType for DateTime

fn static_type() -> Type

Returns the type identifier of Self.
