ANSI C date & time library functions.

[Felix Lee]

Are you allowed to compare time_ts without using difftime()?  Or
should I write "difftime(now, then) < 0" instead of "now < then"?

Can time_t be a pointer (converted to an arithmetic if necessary)?
Imagine
	typedef struct tm * time_t;
time() would allocate a new struct tm and return a pointer to it.
This is assuming you don't compare time_t values directly and don't
try to read or write them.
