: Is it just me who sees inconsistencies in your argumentation here?
No. UTC has no timezones, so is nearly predictable for long stretches
of time. Leap seconds are a random pertebtation that can only be
known as a table. Leap days are know for the next several thousand
years.

: subject?
FreeBSD did it right. End of story.
