It seems to me that this is something that date functions in SQL could do for you. You could either use DATEDIFF with 1/1/1970 (and multiply by seconds per day) to come up with 'seconds since epoch' or you could use DATEPART to dismember the date and calculate 'seconds since epoch' yourself. Either way, if you're already selecting a row from a MSSQL database, it shouldn't require any extra modules. I'm not a MSSQL guy, but this might help you. No good deed goes unpunished. -- (attributed to) Oscar Wilde	[reply]

If you aren't averse to parsing the date yourself and converting it into numbers Time::Local will fix you right up... otherwise there are some Date modules out there that I believe can parse the date and then you can do conversions. Pretty easy to parse that, however and turn Jan into 00 and PM into +12... Update: Time::Local is a module, but I think it is in the Perl core. - Ant - Some of my best work - (1 2 3)	[reply]

suaveant, yes `Time::Local` is indeed in the Perl core. -- vek --	[reply] [d/l]

suaveant's reply has you covered, `Time::Local` would be my choice if you cannot install `Date::*` modules from the CPAN. `use Time::Local; my $epoch = timelocal($sec, $min, $hours, $mday, $mon, $year);` [download] -- vek --	[reply] [d/l] [select]
