Question

What is the data structure for the UNIX time offset variables. If you do a man on time, you will see that time.h is the include file where these data structures are defined. (some are long ints, some are ints).

You can do a little homework on the data structure, post the results, if you don't mind? Thanks. The approach is to take the lenght of the integers and simply calculate what happens as the variables are converted between time subfunctions. You should be able to do this (with system call source code) quite easily.
