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