Display date and time with formatting options and localized dates.

This plugin is an extension of the TWiki variable GMTIME{"format"} (that only allows to show the current date 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.

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>}%


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
    2001-12-31 23:59
    2001-12-31 - 23:59

ISO format
ISO dates may have a timezone specifier, either Z or a signed difference in hh:mm format. For example:
The local timezone will be assumed.

Note: will not handle dates before 1970!
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"}%

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

results in:

Yesterday was Tuesday, 17 Sep 2019

One week from now is %DATETIME{"$wday, $day $month $year" incdays="7"}%

results in:

One week from now is Wed, 25 Sep 2019

To create time-based topics:

"Create TODO topic for tomorrow: [[ToDo$year$mo$day]] ($lwday, $day $lmonth)"

results in:

Create TODO topic for tomorrow: ToDo20190919? (Thursday, 19 September)


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