I mean that the routines in kern_todr.c will pass an "adjusted" time
(using the rtc_offset) to the driver, and apply the rtc_offset from the
driver as well.   This means that if drivers that need an rtc_offset
adjustment, they will get it without ever actually being aware of the
rtc_offset variable.
