Hey, any time's good for Dorf time.
Time seems like a convenient way for us to get an idea of how long something will take, even if it's all relative. You'd think basing the time of day on where the sun is would be a good idea, but no (worked well enough back in the day though). When the seasons occur and when sunrise and sunset occur are always a bit different, and change depending on where you are. Timezones are on unusual borders, probably to force the world to have timezones that shift in half-hours roughly, but even then there's exceptions. Universal Coordinated Time or whatever you call the universal time these days wouldn't make any sense out in space. We've got leap years and leap seconds and daylight savings time to further muck things up. Think of the computer programmers, man. Think of the computer programmers!
Seems like time's a human concept to show the length between a cause and effect. But when nature's behind the cause and effect, as it often is, then there's no guarantee we know how it works because nature's still something we're trying to understand.
