System Time
Main
Hours, minutes,
seconds
Displays and changes the System Time from the Real-
Time Clock.
The RTC Time is displayed in the 24-hour format
[HH:MM:SS]. Each field is selectable with the Tab key.
The + and – keys are used to increment/decrement the
selected field. When changed, values are immediately
committed to the RTC instead of waiting for Save & Exit
Setup/F10 key. The default time is only loaded when the
RTC reports an invalid time, or a battery or CMOS
checksum failure. The default time is not loaded when
other Setup defaults are loaded (F9 key, etc.)
