DateTimePlugin

Introduction

This plugin is an extension of the TWiki variable GMTIME{"format"} (that only allows to show the current date and time).
DateTimePlugin lets you show any date and time before or after 'now', and it will return any part of a date such as the month name.

With DateTimePlugin you can write:
In five days will be: %DATETIME{incdays="5"}% and will have a always coherent phrase.

Date and time are displayed in the local time zone because of the way {DisplayTimeValues} configuration parameter is set. There is no way to specify a time zone in which date and time are displayed.

Syntax Rules

Use %DATETIME{}% to show the current date and time in default date format (as set in configure).

For more options use: %DATETIME{"format" <optional parameters>}%

Parameters

Parameter	Description	Example
"..." or format="..."	Format of date string; see GMTIME{"format"} for formatting variables	%DATETIME{"$wday"}%
date="..."	Any date in one of the following formats: Default TWiki format     31 Dec 2001 - 23:59 TWiki format without time (defaults to 00:00)     31 Dec 2001 Date seperated by '/', '.' or '-', time with '.' or ':' Date and time separated by ' ', '.' and/or '-'     2001/12/31 23:59:59     2001.12.31.23.59.59     2001/12/31 23:59     2001.12.31.23.59     2001-12-31 23:59     2001-12-31 - 23:59 ISO format     2001-12-31T23:59:59 ISO dates may have a timezone specifier, either Z or a signed difference in hh:mm format. For example:     2001-12-31T23:59:59+01:00     2001-12-31T23:59Z In formats other than ISO, GMT time zone is always assumed. This is incosistent with the fact that date and time are displayed in the local time zone. Timestamp (seconds from the epoch)     1009843199 Note: will not handle dates before 1970!	%DATETIME{date="2001/12/31"}%
incdays="..."	Increase the date by any number of days (may be a negative number)	%DATETIME{date="31 Dec 2001" incdays="1"}%
inchours="..."	Increase the date by any number of hours (may be a negative number)	%DATETIME{date="31 Dec 2001 - 07:00" format="$hours" inchours="-1"}%
incminutes="..."	Increase the date by any number of minutes (may be a negative number)	%DATETIME{date="31 Dec 2001" format="$minutes" incminutes="15"}%
incseconds="..."	Increase the date by any number of seconds (may be a negative number)	%DATETIME{date="31 Dec 2001" format="$seconds" incseconds="20"}%
timezone="..."	Specify the time zone in which the result is displayed. Please note that this parameter affects only display. It doesn't affect how the date parameter value is evaluated. As of July 2015, this papameter requires TWiki core downloaded from http://svn.twiki.org to work	%DATETIME{"$hour:$min $tz" timezone="America/New_York"}%

Formatting parameters

See GMTIME{"format"} for general date and time formatting parameters to pass to format. DateTimePlugin supports the following additional paramters:

Overview of all formatting variables

Examples

Yesterday was %DATETIME{"$day $month $year" incdays="-1"}%

results in:

Yesterday was Saturday, 21 Dec 2024

results in:

One week from now is Sun, 29 Dec 2024

%DATETIME{
"Create TODO topic for tomorrow: [[ToDo$year$mo$day]] ($lwday, $day $lmonth)"
incdays="1"
}%

results in:

Create TODO topic for tomorrow: ToDo20241223 (Monday, 23 December)

Limitations

Due to date handling in Perl, DateTimePlugin cannot handle dates earlier than 1970.

Localization

Localized dates are read from configure.
