You need the Time::HiRes module:

Time::HiRes - High resolution alarm, sleep, gettimeofday, interval
timers

You may need to do some time conversions, but as long as you have those
numbers you'll be able to calculate the difference accurately.

Saying that, if you have the time in that format you should be able to
work it out fairly efficiently without any modules at all!
