negative time_t values don't specify a point in time. The talk about
"one specific point of time invalid" is nonsense.

time_t is signed so that it can also be used to store time differences. There
the value -1 is not invalid. It is also necessary that absolute time_t values
(== point in time) are non-negative to avoid overflows when calculating a
difference.
