Well, yes. You're explicitly casting it to a 32-bit value but it can't
hold that much so it gets truncated. But CentOS 5 really shouldn't have
32-bit time_t, and especially not on 64-bit archs, so I don't know
where it's getting its cast from.

It's weird though, because we use the timeval struct provided by
squeue_event_runtime() to check the delay. The delay should always be
< 0 if we overflow the tv_sec field, or huge if we don't. Either way,
we should either run the event as scheduled (and then remove it), or
it shouldn't be at the top of the queue.

Not that I'm overly bothered with what happens when you schedule things
25 years into the future, but bugs that shouldn't exist tend to piss me
off.

Considering the successes of the wars on alcohol, poverty, drugs and
terror, I think we should give some serious thought to declaring war
on peace.
