I'd like to pass you over to the RTC folk, but I don't think they're
very active anymore.

Suffice it to say that the RTC subsystem will set the system date/time
on initialization from the RTC device if one is provided.  All I can
suggest is to look at drivers/rtc and include/linux/rtc.h for the
details.  The MAINTAINERS file should list who is responsible for RTC
stuff as well as a mailing list for it.
