Honestly, time is complicated. Even on Earth, where we rarely have to address synchronization errors due to relativistic effects.

Users care very much about time preserving ordering of events and synchronization of events at disparate locales. They get grumpy if, say, their alarms start going off at what the local restaurants think is 1PM instead of noon because the national government passed a law starting (or stopping) observance of Daylight Savings this year. Similarly (though it's a slower-rolling error), they get grumpy if their alarms start firing at 11:59 and 59 seconds, 11:59 and 58 seconds, etc. when they have them set for noon.

Time is, ultimately, a human construct and software management of it is beholden to the need to get it right from the user's point of view.

You were downvoted unjustly. I think your opinion is mostly valid, but I think people undervalue simplicity because they underestimate knock-on effects of their decisions.
