I have a file that contains start and end times for processes:
     Start BatPrcsDrvr.pl CAEXPENS 1    2009-05-05 01:05:52
     End BatPrcsDrvr.pl CAEXPENS 1 Successfully    2009-05-05 01:05:53
     Start BatPrtnDrop.pl CAEXPENS 1    2009-05-05 01:06:12
     End BatPrtnDrop.pl CAEXPENS 1 Successfully    2009-05-05 01:15:29
     Start BatBackup.pl CAEXPENS 1    2009-05-05 01:21:11
     End BatBackup.pl CAEXPENS 1 Successfully    2009-05-05 01:25:57
etc.
I want to take the time stamp on the End line and compare it to the time stamp on the start line to get the elapsed time.  I am working on this now but not getting very far so any tips would be appreciated.  I will repost if I figure it out first.

use  Time::Local;
$_='Start BatPrcsDrvr.pl CAEXPENS 1    2009-05-05 01:05:52';
@d=/(\d+)-(\d+)-(\d+)\s+(\d+):(\d+):(\d+)/;
$timestamp = timelocal(@d[5,4,3,2],$d[1]-1,$d[0]);

You can also use the CPAN, Date::Manip modules to manipulate date. This also handles text having dates.

See:

Although the Date:: Manip could probably also do what I needed - I took the first authors comments and created a function then imbedded this into my output as follows - this is in a while loop that does other stuff as well but thought I would show how I used the solution - thanks to both of you for your help.

print $fh_output_time_log ("$_", " ", &epoch_time($_) ," \n");

sub epoch_time
{
    local @_;
    @d=/(\d+)-(\d+)-(\d+)\s+(\d+):(\d+):(\d+)/;
    return(sprintf(timelocal(@d[5,4,3,2],$d[1]-1,$d[0])));
}
