I also spotted the same behaviour. If I boot my laptop as MD and afterwards reboot it as PC, local time is not correct but is one hour behind the actual time.
I didn't investigate on this, but it looks like pluto is setting MD time the wrong way (maybe something related to daylight saving settings).
I think this is connected to feature when you select if HW clock is synhronized to real time or just GMT time and then software makes necessarry time zone adjustments ....
anyone that knows where to tackle things ?
