Somebody should inform Mr. or Ms. fpgaminer that there's a Mach layer below the BSD layer, and it uses *unsigned* seconds and microseconds, so that he or she understands why statements such as "... iOS likely is _not_ using u64. It's a BSD derivative, so it's using time_t, which is signed." are based on an incorrect assumption.
