Parameters

{{Localtime}} supports one positional and three named parameters; none are required:

|<time zone> – the first positional (unnamed) parameter, specifies the time zone for which the template is to provide a time output. If omitted, the template displays UTC time. A time zone is identified by an abbreviation of the time zone's standard-time name. Do not use a summertime or daylight saving time abbreviation; they will be ignored and produce an error message.
|df= – date format; an expanded version of the same parameter used in {{time}}. This parameter takes one of four values; values other than these are ignored:
|df=dmy – specifies day month year date format; time in 24-hour format
|df=dmy12 – same as |df=dmy except time in 12-hour AM/PM format
|df=mdy – specifies month day, year format; time in 24-hour format; default when a date format is not specified in the time zone's properties
|df=mdy12 – same as |df=mdy except time in 12-hour AM/PM format
|df=iso – renders the date/time in a form roughly adhering to the ISO 8601 format (seconds omitted)
|df=y – legacy {{time}} parameter, same as |df=dmy
|dst= – when set to no, disables the daylight saving time calculation for the time zone; other values ignored; useful for locations within a time zone that do not observe daylight saving time; Arizona, for example
|align= - the alignment of the template (default right). Can support any HTML alignment.

Usage

Typically, all that is needed is:

{{Localtime|<TZ>}} where <TZ> is one of the supported time zone abbreviations
{{Localtime|MST}}
Basic Clock.png Time: 14:35, June 21, 2024 MDT [refresh]


To change the rendered format:

{{Localtime|MST|df=dmy12}}
Basic Clock.png Time: 2:35 pm, 21 June 2024 MDT [refresh]


{{Localtime|MST|df=mdy}}
Basic Clock.png Time: 14:35, June 21, 2024 MDT [refresh]


{{Localtime|MST|df=iso}}
Basic Clock.png Time: 2024-06-21T14:35 MDT [refresh]


UTC offset

To display the time at a particular UTC offset, specify the UTC time offset as the time zone:

{{time|UTC-07:00}}
Basic Clock.png Time: 2024-06-21T13:35 UTC−07:00 [refresh]


'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,[1] use the time zone's alpha designation:

{{time|M}}
Basic Clock.png Time: 2024-06-22T08:35 M [refresh]


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:

{{time|M++}}
Basic Clock.png Time: 2024-06-22T09:20 M‡ [refresh]


{{time|M+}}
Basic Clock.png Time: 2024-06-22T10:35 M† [refresh]


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 |dst=no:

{{time|MST|dst=no}}
Basic Clock.png Time: 13:35, June 21, 2024 MST [refresh]
– time in Arizona
{{time|MST}}
Basic Clock.png Time: 14:35, June 21, 2024 MDT [refresh]
– 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

{{Localtime}} can produce several error messages. These are:

{{Localtime}} – 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.
{{Localtime}} – 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.
{{Localtime}} – 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.

Adding a new time zone

{{Localtime}} uses Module:Time. 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, 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 pararameter
abbr = '' – (required) the abbreviation of a time zone's standard time as it will be rendered by the template
dst_abbr = '' – the abbreviation of a time zone's daylight saving or summer time as it will be rendered by the template
utc_offset = '' – (required) the offset in hours and minutes from UTC±00:00; has the form: utc_offset = '<sign>hh:mm' where <sign> may be + (optional) or - (required for time zones west of the 0 meridian)
df = '' – one of three keywords dmy, mdy, or iso used to specify date format typically used in the time zone; can be overridden with |df= template parameter
dst_begins = '' – a four word sentence in the form <ordinal> <day name> <in|of> <month name> where:
<ordinal> – any of the words 'first', '1st', 'second', '2nd', ... 'fifth', '5th', or 'last'
<day name> – any of the day names 'Sunday', 'Monday', 'Tuesday', etc.; capitalization is not important but otherwise must be spelled correctly; abbreviations not supported
<in|of> – either of the words 'in' or 'of'
<month name> – any of the month names 'January', 'February', 'March', etc.; capitalization is not important but otherwise must be spelled correctly; abbreviations not supported
dst_ends = '' – (required if dst_begins is specified) same as dst_begins
dst_time = '' – (required if dst_begins 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: dst_time = 'hh:mm UTC'; four digits and the colon are required
dst_e_time = '' – 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: dst_e_time = 'hh:mm UTC'; four digits and the colon are required
article = '' – (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.
