...but don't use this because over the period of seconds since epoch
(January 1 1970 is when UNIX began counting time) it'll not take in to
account leap seconds and the like - so you'll cunningly be out of time
by a little in every calculation.
No. Use the standard POSIX time functions instead - e.g. localtime()
to give you the view of time for where you are in the world.
Cheers,
Jon.
