Using localtime in scalar context and then splitting the scalar around spaces to get a list of (day, month, date, hour and year) values into the hash slice keys...
use strict;
use warnings;
my $time_var = localtime;
my %hash;
my @keys = qw(day month date hour year);
@hash{@keys}= split " ", $time_var;
print "$_->$hash{$_}\n" for keys(%hash);
In addition to all that is suggested, you may want to take a look at modules that can give you more control , like Time::localtime and Time::gmtime.

Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big>
<blockquote> <br /> <dd>
<dl> <dt> <em> <font>
<h1> <h2> <h3> <h4>
<h5> <h6> <hr /> <i>
<li> <nbsp> <ol> <p>
<small> <strike> <strong>
<sub> <sup> <table>
<td> <th> <tr> <tt>
<u> <ul>
-
Snippets of code should be wrapped in
<code> tags not
<pre> tags. In fact, <pre>
tags should generally be avoided. If they must
be used, extreme care should be
taken to ensure that their contents do not
have long lines (<70 chars), in order to prevent
horizontal scrolling (and possible janitor
intervention).
