LOL... I'm OK with us making a choice of timezone to offset into. It just gets my hackles up when folks somehow pretend UTC+offsets are some universal answer to the problem: they aren't.I think it is a misunderstanding that you need a time zone.
You need a fixed reference point in time for when the meeting should happen.
Then it's up to local participants to figure out what they have their watches set to in relation to this.
