description:
correct tm_sec range to be [0-60]

The previous range introduced in time.h rev1.14 was supposed to account
for a mystical "double leap second", which ultimately never could exist
and was a mistaken interpretation from an early ISO C standard whereby
the possibility of two leap seconds within a year was erroneously
interpreted to mean that two leap seconds could occur at once.
