Set system time

The system clock in the protection system is equipped with a standby battery and runs independently
with an accuracy of 50 ppm (4.3 s per day) if not synchronized periodically by an external reference. In
this case, this menu is used for setting the date and time of the protection system. Initially, the date and
time displayed in this menu item are those effective on the PC. The settings in the fields can be
incremented or decremented by clicking on the appropriate arrow to the right of the value. Click on Set
time to set the new date and time on the protection system.
