Indeed, this initiative is about properly informing people about a gameplay session. If I announce a gameplay session today, scheduled for tomorrow but not commenced until wednesday (for whatever reason), does that make the announcement improper?
Yes, in my opinion is does. (As long as today isn't Tuesday which would make tomorrow Wednesday,)
Of course, I meant the proposal to apply only to changes to a later time. There is no doubt for me that changes to an earlier time must be stated at least 24 hours in advance of the new time.
