On Linux/Alpha, time_t is indeed 64 bit (i.e.
printf("%d\n",sizeof(time_t)) results in an '8'). If AbsoluteTime is only
32 bit, then that would definitely cause a problem.

I will apply the above patch, check for other instances of time_t
size assumptions, and see what the result is this afternoon. TTYL.
