TAI64 For All Time
Thursday, September 14, 2006.
From Bernstein's tai64 page:
"Integers 2^63 and larger are reserved for future extensions. Under many cosmological theories, the integers under 2^63 are adequate to cover the entire expected lifetime of the universe; in this case no extensions will be necessary."
Phew!
Dealing with multilog's TAI64 timestamps is always a bit annoying, but I suppose old djb may very well be laughing his head off in 2038. Still, the idea of writing software "for all time" has enough allure to the developer mind that it feels like a trap.
