Why care about POSIX at all? Why not use a non-POSIX UNIX system then? > The time_t type, contains the number of SI seconds since 1970-01-01 > 00:00:00 UTC *ignoring all leapseconds*. Dunno about POSIX, but in UNIX-in-4-capitals which predates POSIX, time_t does NOT mean what you say. UNIX as opposed to POSIX time_t measures the angle by which the hands of a wall clock have rotated since since they displayed midnight 1970-01-01 in Greenwich. It is a wall clock rotation angle and has absolutely nothing to do with SI seconds or physical time interval. > And down at a hairsbreadth, you cannot by looking at a time_t value, > tell the leap second from the second right before it.
