I see leap seconds as regulatory capture by astronomers :D Basically it's convenient for them to have civil time (UTC) never more than 0.5s from UT1.

- masklinn 4y agoAstronomers don’t care, they already need like 5 different clocks. Also the allowable variance between UTC and ut1 is 0.9.
- PeterisP 4y agoExactly - and if astronomers don't care, what other reasons are there to require accurate synchronization of UTC (and civil time) with earth's rotation?
- lostmsu 4y agoConsidering the rate of progress, timestamps might need to be replaced with reference-invariant coordinates.
- moffkalast 4y agoOr one clock that can switch between 5 different times.
- masklinn 4y agoI didn't necessarily mean 5 different timekeeping devices (though that would probably be more convenient in many cases), rather than an astronomer needs to keep track of multiple different "times" concurrently.
