No, it's Doesn't Agree - the issue was very much debated.
True UTC (with leap seconds) didn't cure a problem the committee cared
about, and managed to cause problems they did care about. In short, POSIX
systems have to be able to work in a cave, with no access to the sky or
knowledge of astronomy.

right thing (whatever that may be) don't want to be punished for this by
their less fussy competitors. If one puts safety standards in law and
enforces them, the problem is solved.
