Struct YmdHms 

pub struct YmdHms { /* private fields */ }

Combined Gregorian date + wall time with subsecond precision. Has calendar aware and, when the jiff-tz feature is enabled, timezone aware math functions.

Examples

Creating a YmdHms.

use deep_time::{Dt, Scale};

// clamped to 29
let x = Dt::from_ymd(2000, 2, 30, 0, 0, 0, 0, Scale::UTC).to_ymd();

assert_eq!(x.day(), 29);

Adding a year. 2000 is a leap year and Feb. 29th is possible, but 2001 isn’t a leap year so the day is clamped to the 28th.

use deep_time::{Dt, Scale};

let x = Dt::from_ymd(2000, 2, 29, 0, 0, 0, 0, Scale::UTC).to_ymd();
let x = x.add_yr(1);

assert_eq!(x.day(), 28);

Implementations

impl YmdHms

pub const fn to_dt(&self) -> Dt

Reconstructs a Dt.

pub const fn add_yr(&self, n: i64) -> Self

Adds (or subtracts) whole years, preserving month and day-of-month.

• Uses standard last-day-of-month clamping.
• Negative values subtract.

pub const fn add_mo(&self, n: i64) -> Self

Adds (or subtracts) calendar months. Negative values subtract.

pub const fn add_wk(&self, n: i64) -> Self

Adds (or subtracts) calendar weeks. Negative values subtract.

pub const fn add_days(&self, n: i64) -> Self

Adds (or subtracts) calendar days. Negative values subtract.

pub const fn add_attos(&self, n: i128) -> Self

Adds (or subtracts) attoseconds. Negative values subtract.

pub const fn add_sec(&self, n: i64) -> Self

Adds (or subtracts) whole seconds. Negative values subtract.

pub const fn add_min(&self, n: i64) -> Self

Adds (or subtracts) whole minutes. Negative values subtract.

pub const fn add_hr(&self, n: i64) -> Self

Adds (or subtracts) whole hours. Negative values subtract.

pub const fn yr(&self) -> i64

Returns the year component.

pub const fn mo(&self) -> u8

Returns the month component (1–12).

pub const fn day(&self) -> u8

Returns the day-of-month component (1–31, depending on month/year).

pub const fn hr(&self) -> u8

Returns the hour component (0–23).

pub const fn min(&self) -> u8

Returns the minute component (0–59).

pub const fn sec(&self) -> u8

Returns the second component (0–60). The value 60 only occurs during a positive leap second on Scale::UTC / UtcSpice / UtcHist.

pub const fn attos(&self) -> u64

Returns the attosecond (sub-second) component (0 ≤ attos < 10¹⁸).

pub const fn scale(&self) -> Scale

The time scale that the object was created on.

pub const fn iso_yr(&self) -> i64

Returns the ISO week year (can differ from the calendar year near January 1 / December 31).

pub const fn iso_wk(&self) -> u8

Returns the ISO week number (1–53). Weeks start on Monday; week 1 is the week containing the first Thursday of the year.

pub const fn day_of_yr(&self) -> u16

Returns the day of the year (ordinal date), 1-based (Jan 1 = 1, Dec 31 = 365 or 366 in leap years).

pub const fn wkday(&self) -> u8

Returns the weekday number according to Dt::jd_to_wkday (typically 0 = Sunday … 6 = Saturday; exact convention is defined by the Julian Day helper).

pub const fn wk_of_yr_sun(&self) -> u8

Returns the week of year number when weeks are considered to start on Sunday (US-style numbering).

pub const fn wk_of_yr_mon(&self) -> u8

Returns the week of year number when weeks are considered to start on Monday.

impl YmdHms

pub fn add_yr_tz(&self, n: i64, tz: &str) -> Result<Self, DtErr>

Adds the given number of years in the specified IANA timezone, respecting timezone rules (including DST) and proper calendar arithmetic.

Errors

• Jiff only supports years in the range -9999..=9999. Years outside this range will return a DtErr.
• If Jiff cannot find the timezone name or if applying the timezone would cause the jiff::Zoned to be outside the -9999..=9999 year range then a DtErr with DtErrKind::InvalidTimezoneOffset is returned.

pub fn add_mo_tz(&self, n: i64, tz: &str) -> Result<Self, DtErr>

Adds the given number of months in the specified IANA timezone, respecting timezone rules and calendar month-end clamping.

Errors

• Jiff only supports years in the range -9999..=9999. Years outside this range will return a DtErr.
• If Jiff cannot find the timezone name or if applying the timezone would cause the jiff::Zoned to be outside the -9999..=9999 year range then a DtErr with DtErrKind::InvalidTimezoneOffset is returned.

pub fn add_wk_tz(&self, n: i64, tz: &str) -> Result<Self, DtErr>

Adds the given number of weeks in the specified IANA timezone.

Errors

• Jiff only supports years in the range -9999..=9999. Years outside this range will return a DtErr.
• If Jiff cannot find the timezone name or if applying the timezone would cause the jiff::Zoned to be outside the -9999..=9999 year range then a DtErr with DtErrKind::InvalidTimezoneOffset is returned.

pub fn add_days_tz(&self, n: i64, tz: &str) -> Result<Self, DtErr>

Adds the given number of calendar days in the specified IANA timezone.

pub fn add_min_tz(&self, n: i64, tz: &str) -> Result<Self, DtErr>
