Question
Perl Time Stamp Calculation
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.

You can also use the CPAN, Date::Manip modules to manipulate date. This also handles text having dates.
See:
http://search.cpan.org/~sb
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+(\
return(sprintf(timelocal(@
