Of course. Local time is always better known than UTC. But any given
local time is only going to be known in its own locality. I would bet
that the people in Russia who know Eastern Standard Time, or the
people in California who know Moscow time, would be quite low.

I know, on both counts, because I'm a wonk. But those specifics are
part of what I would elide, along with leap seconds and relativity,
when explaining a scheduling system. (Let's face it - nobody's going
to schedule a meeting to such accuracy that any of it will matter.)
Time is a lot messier than most people need to care about.
