ZonedDateTime

Ƭ ZonedDateTime: Format["YYYY-MM-DDThh:mm-ss[.sss]+00:00[TimeZoneName]"] & string

An Iso.ZonedDateTime is a timezone-aware date/time type that represents a real event that has happened (or will happen) at a particular instant from the perspective of a particular region on Earth. As the broadest Iso type, Iso.ZonedDateTime can be considered a combination of a Iso.TimeZone, Iso.Instant, and Iso.DateTime.

As the only Iso type that persists a time zone, Iso.ZonedDateTime is optimized for use cases that require a time zone:

Arithmetic automatically adjusts for Daylight Saving Time, using the rules defined in RFC 5545 (iCalendar) and adopted in other libraries like moment.js.
Creating derived values (e.g. change time to 2:30AM) can avoid worrying that the result will be invalid due to the time zone's DST rules.
Functions are available to easily measure attributes like "length of day" or "starting time of day" which may not be the same on all days in all time zones due to DST transitions or political changes to the definitions of time zones.
It's easy to flip back and forth between a human-readable representation (like Iso.DateTime) and the UTC timeline (like Iso.Instant) without having to do any work to keep the two in sync.
A date/time, an offset, and a time zone are represented in a single string that can be sorted alphabetically by the exact time they happened. This behavior is also helpful for developers who are not sure which of those components will be needed by later readers of this data.
Multiple time-zone-sensitive operations can be performed in a chain without having to repeatedly provide the same time zone.

An Iso.ZonedDateTime can be losslessly converted into every other Iso type except Iso.Duration. Iso.Instant, Iso.DateTime, Iso.Date, Iso.Time, Iso.YearMonth, and Iso.MonthDay all carry less information and can be used when complete information is not required.

The Iso.ZonedDateTime functions are a superset of Iso.DateTime functions, which makes it easy to port code back and forth between the two types as needed. Because Iso.DateTime is not aware of time zones, in use cases where the time zone is known it's recommended to use Iso.ZonedDateTime which will automatically adjust for DST and can convert easily to Iso.Instant without having to re-specify the time zone.

now

▸ now(timeZone?): ZonedDateTime

This method gets the current date, time, time zone, and time zone offset according to the system settings. Optionally a time zone can be given in which the time is computed, instead of the current system time zone.

Parameters

Name	Type	Description
`timeZone?`	`string`	The time zone to get the current date and time in as a string. If not given, the current system time zone will be used.

Returns

ZonedDateTime

an Iso.ZonedDateTime string representing the current system date, time, time zone, and time zone offset.

Defined in

types/IZonedDateTimeFns.ts:18

currentTimeZone

▸ currentTimeZone(): string

This method gets the current system time zone. This will usually be a named IANA time zone, as that is how most people configure their computers.

Returns

string

a string representing the time zone according to the current system settings.

Format of the string is based on Unicode Technical Standard #35: https://www.unicode.org/reports/tr35/tr35-dates.html#Date_Field_Symbol_Table with a few additions (see note 7 below the table).

Notes:

Any sequence of the identical letters is a pattern, unless it is escaped by the single quote characters (see below). If the sequence is longer than listed in table (e.g. EEEEEEEEEEE) the output will be the same as default pattern for this unit, usually the longest one (in case of ISO weekdays, EEEE). Default patterns for units are marked with "2" in the last column of the table.
format("2017-11-06", 'MMM') //=> 'Nov'
format("2017-11-06", 'MMMM') //=> 'November'
format("2017-11-06", 'MMMMM') //=> 'N'
format("2017-11-06", 'MMMMMM') //=> 'November'
format("2017-11-06", 'MMMMMMM') //=> 'November'
Some patterns could be unlimited length (such as yyyyyyyy). The output will be padded with zeros to match the length of the pattern.
format("2017-11-06", 'yyyyyyyy') //=> '00002017'
QQQQQ could be not strictly numerical in some locales. These tokens represent the shortest form of the quarter.
The main difference between y and u patterns are B.C. years:
Year y u
AC 1 1 1
BC 1 1 0
BC 2 2 -1
Also yy always returns the last two digits of a year, while uu pads single digit years to 2 characters and returns other years unchanged:
Year yy uu
1 01 01
14 14 14
376 76 376
1453 53 1453
These patterns are not in the Unicode Technical Standard #35:
- i: ISO day of week
- I: ISO week of year
- o: ordinal number modifier
- P: long localized date
- p: long localized time

Year	`y`	`u`
AC 1	1	1
BC 1	1	0
BC 2	2	-1

Year	`yy`	`uu`
1	01	01
14	14	14
376	76	376
1453	53	1453

Characters are escaped using single quote symbols (').

example

// Represent 11 February 2014 in middle-endian format:
var result = format("2014-02-11T00:00:00+00:00[UTC]", 'MM/dd/yyyy')
//=> '02/11/2014'
