Seems reasonable and very unlikely to be harmful. That being said,
this function really ought to be considered deprecated -- 32-bit
time_t is insufficient.
Do you get even better code if you move the read into the if statement?
Euh ...
How can you return t when time pointer is NULL if you read t only when
time pointer is not NULL ?
