Will Clockwise move a meeting that happens that same day?
No. Clockwise will never move a meeting the same day it occurs by itself.
Clockwise needs 20 hours between the time of movement (4 PM for your org's majority timezone) and the meeting to occur, so a meeting will only move if it is after 12 PM the next day.
Note: Clockwise will not move meetings proactively the same day it occurs. For urgent meetings, Clockwise users can prompt Prism to approve meetings be moved same-day to accommodate necessary schedule changes. These changes only occur when a user says an event must happen 'today'.
