Re: [mpiwg-tools] Meeting today?

Dear all, as nobody joined the running call, and there is no feedback on whether the 5pm call makes sense, I would skip today's call. Next week should be back in the normal schedule.

Meeting today?
by Marc-André Hermanns 23 Mar '26

23 Mar '26

Dear all, sorry for the timezone confusion. Today, we have still have the US/Europe timezone skew due to summer time changes. The *normal time* of our meeting would be *now*, which is 10 am CT (and currently 16:00 in Germany). Last week I sent the wrong reminder time, so we had the meeting at 5 pm CET (which was 11 am CT). The question is: would everyone be OK with meeting at 11am CT/5pm CET or should we skip today? Next week the normal schedule is in place again, as Europe changes to Summer time next weekend.
