Actually time_t is normally an integer storing number of seconds since
1970.
localtime converts the number of seconds to a struct tm with time adjusted
for time zone and daylight savings.
gmtime converts the same number of seconds to a struct tm filled in with
UTC time, i.e. time-zone GMT without daylight savings.
For some systems, you might also do gettimeofday() to get sub-second time
resolution.
