Is there a good reason for this? I ask the question because the x86
/dev/rtc driver says:
* Only the values that we read from the RTC are set. We leave
* tm_wday, tm_yday and tm_isdst untouched. Note that while the
* RTC has RTC_DAY_OF_WEEK, we should usually ignore it, as it is
* only updated by the RTC when initially set to a non-zero value.
So it seems the established modus operandi for RTC interfaces is "don't
trust wday, yday and isdst".
