: IANL, but based on a few documents I've seen
: Canadian standard time is provincial, not federal.
: Quebec adopted UTC on 2007-01-01, and the others have not.

I'd wager that UTC, whatever its realization, would likely trump any
locally written laws. After all, UTC has been a widely accepted
approximation of the local laws that's attained the force of law
through repetitive use (how many real-time realizations of UT1 are
propagated, in comparison to UTC). So underlying technical changes to
UTC may not change that. It would take a long, and complicated, legal
argument to show that UT1 is what should be used (even though nobody
knows what it is, day to day). Given the current miss-mash of legal
rulings around software, I'd guess that this wouldn't be a "clear cut"
ruling that people in this group have suggested.
