A lot of people don't think the current approach is so great.

It shares with time zones the problem that you cannot tell what
the UNIX timestamp will be for a particular future time.  If
you want to have something happen at, say, July 2 2025 at 12:00 UTC
you can guess what the timstamp for that will be, but if there's
another leapsecond or two, you'll be wrong.

Life would be a lot easier for everyone except a handful of
astronomers if we forgot about leap seconds and adjusted by a full
minute every couple of centuries.
