Kontron KBox C-101 - Manual (Page 18)

7. System Overview KBox C-101 – User’s Guide (Version 2.00)
If the time is not valid this is indicated by a status bit in the RTC registers. For details see the RV-8564 application manual.
To get the maximum buffer time it is necessary to have the system a certain time powered on. This ensures
that the buffer capacitors are fully loaded.
The buffer time depends on the ambient temperature and on how long the box is connected to its power
supply.
7.1.2. Setting the RTC
During startup, the uEFI performs a comparison of chipset clock and external RTC and sets the chipset clock accordingly if
the RTC time is valid. Further it is possible to set the time manually by accessing the RTC over the SMBus.
