In C there's the ctime function and friends.  Kind of a pain to use.
I'm betting PHP or Perl has something handy just for this.
(I know "time()" in PHP gives the current time in seconds since Unix epoch,
which was 1970, perhaps it's flexible about epoch and/or using an arbitrary
date/time)

What environment, specifically, are you in?  Writing Python?  Perl?
Just sitting at a shell?
