These days the contents of the timezone and dstflag fields are unde- fined. RETURN VALUE This function always returns 0. BUGS This function is obsolete. Don't use it. If the time in seconds suf- fices, time(2) can be used; gettimeofday(2) gives microseconds; clock_gettime(3) gives nanoseconds but is not yet widely available. Under libc4 and libc5 the millitm field is meaningful. But early glibc2 is buggy and returns 0 there; glibc 2.1.1 is correct again.
