Important!
The RTC mode is used only for test purposes!
RTC behaviour if mode=ON:
- A Valid time source has to be available for RTC first time set
- On startup the RTC is used to set the DTS time.
- As soon as an other source is available the DTS swiches to this source
- A time jump has be expectet on such source switch
Important!
For the high precision time signal outputs (1PPS, 10MHz, ToD,...), the
RTC mode should never be switched on!
Important!
RTC cannot handle Leap second
