What 2 PM Eastern means
Denver is at lunch while the East Coast is in its mid-afternoon. About three hours of shared office time remain because most East Coast offices close at 5 PM Eastern. That is 3 PM Mountain. A call at 1 PM Mountain still leaves both sides time to follow up the same day. The meeting planner for Mountain and Eastern teams shows every shared hour.
