Because if your unix time is stored in a ulong, for whatever reason, you  
may then have to cast to call this function.

time_t implicitly casts to ulong, no matter the system-defined size of  
time_t.  It's also more future-proof, for dates past 2038.

Is there a specific reason to disallow accepting ulong?
