If can live with its limitations(1), you could try something like this:

#! perl -slw use strict; use constant MONTHS => { qw[ Jan 0 Feb 31 Mar 59 Apr 90 May 120 Jun 151 Jul 181 Aug 212 Sep 242 Oct 272 Nov 303 Dec 334 ] }; sub str2epoch { my( $d, $m, $y, $H, $M, $S ) = $_[0] =~ m[^.... (\d\d) (...) (\d\d\d\d) (\d\d):(\d\d):(\d\d)] or die "Bad format $_[0]"; my $leaps = int( ($y - 1970) / 4 + 0.5 ); (((($y-1970)*365 +$leaps+MONTHS->{$m}+($d-1))*24 +$H)*60 +$M)*60 + +$S; } my $date = 'Fri, 01 Mar 2013 01:21:14 +0000';; print str2epoch( $date ); print scalar localtime str2epoch( $date ); print scalar localtime str2epoch( 'Fri, 12 Jul 2013 01:20:34' );; __END__ C:\test\primes>..\ 1362100874 Fri Mar 1 01:21:14 2013 Fri Jul 12 02:20:34 2013

And if you need a little more you might parse the numbers with unpack instead of the regex engine.

1 Limitations include:

  • No leap seconds;
  • No daylight savings;
  • No timezones;
  • Only works for another 87 years.

Use:  <p> text here (a paragraph) </p>
and:  <code> code here </code>
to format your post; it's "PerlMonks-approved HTML":

  • Are you posting in the right place? Check out Where do I post X? to know for sure.
  • 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).
  • Want more info? How to link or How to display code and escape characters are good places to start.
