Never, that's the trouble.
time_t is better defined as:
d * 86400 + min(rs, 86399)
where:
d = Number of complete days since 1970-01-01H00:00:00Z
rs = number of seconds since UTC midnight.
Eliminating leapseconds would make it correct however.

Never attribute to malice what can adequately be explained by incompetence.
