[kolla] Moving weekly meeting time

Hello Koalas!

As agreed on the weekly meeting yesterday - we’re moving the weekly Kolla Wednesday meeting one hour earlier starting next week (March 30th). The reason for this change is daylight savings time change (Sunday March 13th for US, and Sunday March 27th for EU).
