Now you can take time on the go with this DC-150-GPS-P portable totally battery operated time of day clock that is mounted on an all aluminum trailer. Simply remove the display and drive to you next location. (for open road remove one bolt and the display slides off for easy back seat storage).
Once the Clock has been set in place power it up and it finds the time of day automatically, synchronizing to the atomic time of day clock in boulder Colorado. User selectable time zones and daylight savings enable disable. 120VAC power also available
