You misunderstood what Michael asked Tom! (Perhaps on purpose as a joke?)
He was asking when will the activity begin - and please give the answer in UTC to avoid confusion.
I would suggest you take a look at the Alerts on SotaWatch3 Michael and see there when people expect to be on.
Will you be activating yourself or chasing from home?

It looks like a lot of people are already committed to take part!
