Sure there is a way:  Ask the user (and save the answer for the next
time).

If we can put whatever we like in the struct, then I think it would be
good to allow RTC_OFFSET to be set there.  RTC_OFFSET is the main
reason why the GENERIC kernel isn't really generic.

(It should be an optional field of course, if not set then use the
 value compiled into the kernel.)
