Timepieces are probably inaccurate in your ED, and that can have serious consequences during critical events such as major trauma and cardiac arrest resuscitation. During resuscitations, multiple timepieces are used, and many events occur in a short period of time. Inaccuracies make it impossible to reconstruct the order of events accurately, which increases liability risks in the event of a lawsuit. Staff can synchronize their timepieces by calling the local number that announces the atomic clock time every 10 seconds; ideally, however, all clocks should be set universally by a central server.
