c/c++ programing quetions

I have been looking for a few days now trying to find a way to get the time and data from c/c++. I just can't find it.

Does anyone have any ideas on how to do or where I could find a time and data function.

Look at the methods in <time.h>

Get the number of seconds since the beginning of 1980.
Convert it to whatever format you want.

Thank you
