README 

The RTC driver component provides access to the CMOS RTC on x86 via
the Rtc session. On base-linux 'gettimeofday' is used.

The component will use the content of the 'set_rtc' ROM if the
'allow_setting_rtc' attribute in the 'config' node is set to 'yes'
to allow setting the RTC. A valid ROM must contain a top node with
the following attributes:

* 'year' (e.g. 2019)
* 'month'  (1 - 12)
* 'day'    (1 - 31)
* 'hour'   (0 - 23)
* 'minute' (0 - 59)
* 'second' (0 - 59)

The component will always use 24H mode and relies on the BIOS/firmware
to do the right thing regarding the year.
