This is how the RTC framework used to handle it before the referenced patch in my original mail, so a reversal (conditional on 32bit) would solve that part of the problem. It also looks like Miroslav's patch will handle the other cases of a accidental user initiated set of a bad date or a maliciously set NTP. Though, from my point of view, a wrap-around to 1970 would be just as valid as a jump one week in the past.
