By a narrow margin, 3rd Tuesday of the month, 2p UTC turns out to be favored by 9 of us.
That's 3pm London and 4pm CET. Here's a zoom link for May 17th -- I should be able to make this slot after all.
I will send out again in a reminder a few days out from it.
One agenda item that has come as a suggestion recently is the addition of a certainty or confidence attribute for "when" statements. Oddly (?) certainty is in the spec for space (geometry) but not time.
