Template:Time/doc

This template displays the current time in a parameter-specified time zone. The time is calculated based on the offset from UTC for the specified time zone taking into account whether daylight saving time is currently active in that time zone.

Note: Most Wikipedia pages display a cached version of the page to reduce server load, so the template will only display the current time as of when the page was last parsed. You can refresh the displayed time by clicking the [refresh] link.

Usage
Typically, all that is needed is:
 * where  is one of the supported time zone abbreviations
 * June 29, 2024
 * June 29, 2024

To change the rendered format:

UTC offset
To display the time at a particular UTC offset, specify the UTC time offset as the time zone:
 * June 29, 2024
 * June 29, 2024

'UTC', a sign character, two hour digits, a colon, and two minute digits are required. Accepted sign characters are: '+', '-' (hyphen), '±', and '−' (minus).

Military/nautical time zones
To display the time at a particular military or nautical time zone, use the time zone's alpha designation:
 * June 29, 2024
 * June 29, 2024

Some military and nautical time zone designators are extended with an asterisk (*), a dagger (†), or double dagger (‡). When writing this template for designators that are extended with a dagger or double dagger, use '+' and '++' respectively:
 * June 29, 2024
 * June 29, 2024
 * June 29, 2024
 * June 29, 2024

Daylight saving time
Daylight saving time (DST) calculations are automatic for those time zones where it is observed. There are locales that do not observe DST within time zones where it is generally observed. To render the correct time for a non-observant locale, set no:
 * June 29, 2024 – time in Arizona
 * June 29, 2024 – but, time on the Navajo Nation in Arizona
 * June 29, 2024 – but, time on the Navajo Nation in Arizona
 * June 29, 2024 – but, time on the Navajo Nation in Arizona

The opposite case is not supported. For places like Thule Air Base in Greenland, which observes US DST rules while WGT observes EU DST rules, a time zone properties table will be needed in Module:Time. See §Adding a new time zone.

Error messages
can produce several error messages. These are:
 * {{time} } – both of &#124;df-cust-a= and &#124;df-cust-p required – when defining a custom format for am (or pm) time, you must also define a custom format for pm (or am) time
 * June 29, 2024 – error calculating dst timestamps – indicates an internal error because one or more of the following time zone properties is malformed: UTC offset, DST begin or end definition. To resolve this error make sure that the time zone's properties are correct.
 * June 29, 2024 – incomplete definition for ... – indicates an internal error because one or more of the following time zone properties is missing: DST begin or end definition, DST event time, time zone article. To resolve this error supply the missing properties.
 * {{time} } – invalid date format &lt;format> – value assigned to df is not one of the defined format strings; ss §Parameters
 * June 29, 2024 – invalid use of ± - the symbol ± is being used when the minute and hour offsets aren't 00:00
 * {{time} } – malformed or incomplete _TEST_TIME_ – value assigned to this parameter must either have the format: YYYY-MM-DDThh:mm:ss where all except 'T' are digits, or YYYYMMDDhhmmss
 * {{time} } – unknown timezone – the time zone positional parameter is not one of the supported time zone abbreviations. To resolve this error check the parameter's spelling or add the time zone's properties to the module.  See §Adding a new time zone.

Adding a new time zone
uses Module:Time/data. In that module, is a table of tables, the data structure that specifies the properties of the individual time zones. A blank time zone properties table has this form: [] = {	abbr = , dst_abbr = '', utc_offset = '', df = '', dst_begins = '', dst_ends = '', dst_time = '', dst_e_time = '', article = '' },

To add a new time zone to Module:Time/data, add the appropriate information inside the single quotes. If a property does not apply, leave the quotes empty. The rules for each property are:
 * – (required) the abbreviation of a time zone's standard time; must be lower case; this is the value that will be used in the template's time zone parameter
 * – (required) the abbreviation of a time zone's standard time as it will be rendered by the template
 * – the abbreviation of a time zone's daylight saving or summer time as it will be rendered by the template
 * – (required) the offset in hours and minutes from UTC±00:00; has the form:  where   may be   (optional) or   (required for time zones west of the 0 meridian)
 * – one of three keywords,  , or   used to specify date format typically used in the time zone; can be overridden with df template parameter
 * – a four word sentence in the form        where:
 * – any of the words 'first', '1st', 'second', '2nd', ... 'fifth', '5th', or 'last'
 * – any of the day names 'Sunday', 'Monday', 'Tuesday', etc.; capitalization is not important but otherwise must be spelled correctly; abbreviations not supported
 * – either of the words 'in' or 'of'
 * – any of the month names 'January', 'February', 'March', etc.; capitalization is not important but otherwise must be spelled correctly; abbreviations not supported
 * – (required if  is specified) same as
 * – (required if  is specified) the time that daylight saving time begins; usually local time; when DST begins at a specified time UTC (European Summer Time for example) use:   ; four digits and the colon are required
 * – the time that daylight saving time ends if different from the time it begins; usually local daylight saving time ; when DST ends at a specified time UTC use:  ; four digits and the colon are required
 * – (required) the title of a Wikipedia article that is appropriate to the timezone; do not include wikimarkup

The table-of-tables is organized east (plus UTC offsets) then west (minus UTC offset), by offset hours, and then alphabetically by time zone positional parameter name.

Adding a new alias
You may also want to add an alias of a timezone:

[] = {tz = },

To add a new time zone to Module:Time/data, add the appropriate information inside the single quotes.
 * – (required) the abbreviation of a time zone's alias. This must be lower case.
 * – (required) the abbreviation of the time zone that's already in the code. This must be lower case

The table-of-tables is organized east (plus UTC offsets) then west (minus UTC offset), and by if it's a DST offset or if it's not.
