When the mapping between a time_t and a "human readable format" (hours, minutes, seconds, etc) takes into account extra leap seconds. You could use time_t underneath, if that's what you really wanted to do.
As my co-worker once put it, "time is a four letter word."
At the very least, there is a need for showing the occasional 61st second of a minute, and adding a time and timedelta where leap seconds is taken into account.
