Not quite. Check out "man gmtime" for one way that POSIX represents time.
Specifically:
struct tm {

int tm_sec; /* Seconds (0-60) */
gmtime() is perfectly capable of reporting 61 seconds in a minute.
Failure to account for this causes mnay problems.
What it does not do well is accounting for leap seconds that are in
the past or future.

But gpsd and ntpd try real hard to be correct. Sadly, with leap smear,
there is no consensus on what is 'correct'.
