OT: I am wondering about the 9:05 time. Is this a new thing to start meetings after the full hour? During the pandemic I noticed that many meeting are organized without any break in between. So at my company we tried to set the default end of meetings to X:25 and X:50 but it doesn't seem to help much (as everybody is used to running meetings to the full hour). So I am wondering if setting the start to X:05 might help?
