Most 64-bit systems use a 64-bit int. All of the 64-bit Linux systems
that I've used use a signed 64-bit int. Some systems use a 64-bit
unsigned int. Some use a double. The only way to know for sure is to
look at their definition of time_t in time.h, as provided by the system.
http://en.wikipedia.org/wiki/Time_t is as good a starting point as any.
The precise words from the Open Group Base standard are:
time_t and clock_t shall be integer or real-floating types.
The usage of time_t in various functions is specified, but range and
type is not defined.
