Description

This PR changes the timezone in the open meetings to fit the related schedule. For the regular meetings, we have to switch again in March ;)

instead of having to change them every time could it worth to add a disclaimer explaining how to interpret those?

e.g.
in the schedule: Every Tuesday from 10:30 am to 11:00 am

just before the meeting list:

All the times are shown in:
- UTC+2 (CEST) between the last Sunday of March and the last Sunday of October
- UTC+1 (CET) the rest of the year.

(note aside: I would also switch to the 24hour format (without am-pm))

thx. added the information. i didnt delete am/pm, since i was not sure what is the default way we should mention it. No hard feelings... but is this the official way to dsplay the time?

LGTM

I guess there's no official way, some countries use the AM/PM, while the rest of the world uses the 24h format.
As an engineer, I see the second one as definitely better, as it is clearer and leaves less space for misinterpretation. (same thoughts about the DD/MM vs MM/DD argument).
But, no strong feelings here, let's get it merged as it is ;)
