It means that the count of seconds stored in time_t includes every
broadcast full-second tick since 1970-01-01T00:00:00, that is,
including the leap seconds but not including the fractional second
step that happened at 1972-01-01T00:00:00.
If I am not mistaken, this means that the value in time_t desired by
the "right" zones is the same as is specified by a system which sets
its clock using a device conforming to IEEE 1588 (PTP).
