Time Comparision

[pho01]

How would you do time subtraction and time comparision?
I'm looking to perform the following:

For example:
Time subtraction:
3 hours off
20060308 02:00:00.000 - 3 hours => 20060307 23:00:00.000

1 day off
20060308 02:00:00.000 - 1 day => 20060307 02:00:00.000

Time comparision:
How to compare:
20060308 02:00:00.000 > 20060302 02:00:00.000

Thanks!

try using Date::Manip from CPAN. The function you're looking for is most probably DateCalc.

Or, you can write a function to convert everthing to epoc seconds, do your math, and then convert back. I do this on occassion with timelocal and localtime.
