To be honest, this would only work if time(3), gettimeofday(2), utimes(2), ...
are changed also together with all time_t users.

I was amazed to see how many places are affected when I convinced the FreeBSD
people to use a 64 bit time_t instead of a 32 bit one in the 64 bit sparc 
version of FreeBSD a few years ago. This is no simple change as e.g. even 
timeouts from init and svc.startd are affected. The result on FreeBSD was that
cleanly written code only needed a recompile. In case if a 32 bit OS, things 
look different as more potential printf formats are affected.
