I don't have GNU
date on my system. The Linux
date man page available on this forum says:
Quote:
DATE STRING
The --date=STRING is a mostly free format human readable date string such as "Sun, 29 Feb
2004 16:21:42 -0800" or "2004-02-29 16:21:42" or even "next Thursday". A date string may
contain items indicating calendar date, time of day, time zone, day of week, relative
time, relative date, and numbers. An empty string indicates the beginning of the day.
The date string format is more complex than is easily documented here but is fully
described in the info documentation.
Since you have access to the GNU
date utility, I assume you can find "
the info documentation" that fully describes the date string format on your system. It isn't available on my system.
The main problem you'll need to resolve is how to tell the difference between an MMDD versus DDMM input or how to rearrange your input into the order that date will interpret correctly for the input format you're given.

NAME
Template::Plugin::Date - Plugin to generate formatted date strings
SYNOPSIS
[% USE date %]
# use current time and default format
[% date.format %]
# specify time as seconds since epoch
# or as a 'h:m:s d-m-y' or 'y-m-d h:m:s' string
[% date.format(960973980) %]
[% date.format('4:20:36 21/12/2000') %]
[% date.format('2000/12/21 4:20:36') %]
# specify format
[% date.format(mytime, '%H:%M:%S') %]
# specify locale
[% date.format(date.now, '%a %d %b %y', 'en_GB') %]
# named parameters
[% date.format(mytime, format = '%H:%M:%S') %]
[% date.format(locale = 'en_GB') %]
[% date.format(time = date.now,
format = '%H:%M:%S',
locale = 'en_GB) %]
# specify default format to plugin
[% USE date(format = '%H:%M:%S', locale = 'de_DE') %]
[% date.format %]
...
DESCRIPTION
The "Date" plugin provides an easy way to generate formatted time and date strings by delegating to the "POSIX" "strftime()" routine.
The plugin can be loaded via the familiar USE directive.
[% USE date %]
This creates a plugin object with the default name of '"date"'. An alternate name can be specified as such:
[% USE myname = date %]
The plugin provides the "format()" method which accepts a time value, a format string and a locale name. All of these parameters are
optional with the current system time, default format ('"%H:%M:%S %d-%b-%Y"') and current locale being used respectively, if undefined.
Default values for the time, format and/or locale may be specified as named parameters in the "USE" directive.
[% USE date(format = '%a %d-%b-%Y', locale = 'fr_FR') %]
When called without any parameters, the "format()" method returns a string representing the current system time, formatted by "strftime()"
according to the default format and for the default locale (which may not be the current one, if locale is set in the "USE" directive).
[% date.format %]
The plugin allows a time/date to be specified as seconds since the epoch, as is returned by "time()".
File last modified: [% date.format(filemod_time) %]
The time/date can also be specified as a string of the form "h:m:s d/m/y" or "y/m/d h:m:s". Any of the characters : / - or space may be
used to delimit fields.
[% USE day = date(format => '%A', locale => 'en_GB') %]
[% day.format('4:20:00 9-13-2000') %]
Output:
Tuesday
A format string can also be passed to the "format()" method, and a locale specification may follow that.
[% date.format(filemod, '%d-%b-%Y') %]
[% date.format(filemod, '%d-%b-%Y', 'en_GB') %]
A fourth parameter allows you to force output in GMT, in the case of seconds-since-the-epoch input:
[% date.format(filemod, '%d-%b-%Y', 'en_GB', 1) %]
Note that in this case, if the local time is not GMT, then also specifying '%Z' (time zone) in the format parameter will lead to an
extremely misleading result.
Any or all of these parameters may be named. Positional parameters should always be in the order "($time, $format, $locale)".
[% date.format(format => '%H:%M:%S') %]
[% date.format(time => filemod, format => '%H:%M:%S') %]
[% date.format(mytime, format => '%H:%M:%S') %]
[% date.format(mytime, format => '%H:%M:%S', locale => 'fr_FR') %]
[% date.format(mytime, format => '%H:%M:%S', gmt => 1) %]
...etc...
The "now()" method returns the current system time in seconds since the epoch.
[% date.format(date.now, '%A') %]
The "calc()" method can be used to create an interface to the "Date::Calc" module (if installed on your system).
[% calc = date.calc %]
[% calc.Monday_of_Week(22, 2001).join('/') %]
The "manip()" method can be used to create an interface to the "Date::Manip" module (if installed on your system).
[% manip = date.manip %]
[% manip.UnixDate("Noon Yesterday","%Y %b %d %H:%M") %]
