don't forget that for high speed systems (more than 1Hz) time must have fraction of seconds, like microtime() in php with 6 digits after seconds

Ticks are easy in .NEt, but I'm much more concerned about the "meaning" of that specific time.

If my server runs DST but one of the clients is on CET, and the client sends 2007-07-12 12:00 AM, what does it mean? 12:00 in DST or CET?

We either should declare that absolute expiration should treated as UTC, or get rid of it and use relative expirations.


Yes, either of these makes me more happy than the current situation.

I generally don't like absolute times unless absolutely required,
though. Relative time is robust to all sorts of things for free like
massively mismatched clocks and, as mentioned, time zones.
