[tc] weekly meeting time

Hi folks:

Given that we've landed the change to start having weekly meetings again, it's time to start picking a time:

A few people also mentioned they wouldn't mind taking the current office hours time towards that, I guess we can try and come to an agreement if we want to do that here (or simply by voting that time on the Doodle).

Thanks, Mohammed
