Mission Control Clock (MCCLOCK) is a countdown clock such as the ones found in the firing rooms at the Kennedy Space Center. At any one time, a user can tell when an event is about to take place or how long it has been since an event occurred. MCCLOCK can display up to 21 events at one time along with the Local, Greenwich Means Mission Elapse Time and End of Mission times. Other functions include clocks for tracking stations' time of day, secondary timers to let you know such things as when a launch window closes, and a screen to let you know the date, time, and mission elapse time that an event will take place
