I've always thought that (1) teams should be free to set their
meetings either at strict UTC, or following DST however they can
agree; and (2) computers work in UTC, and humans work on wall clocks.
My $DAYJOB schedule, for example, @3:00pm on a Thursday doesn't change
suddenly in the spring and fall to accommodate UTC. The same meeting
I had at 3:00pm the week before stays at 3:00pm and moves according to
UTC.
So in short, I'm for staying on human time. The only time we have to
worry about a difference is when only some people are on DST and not
others. Then there's a chance for confusion, so the meeting page
should set the policy.
