As I've said before, it's how the clock is _always_ set when I acquire a 
computer, either new or old. I've not seen even new mobos with the wrong 
time in them, though I haven't looked closely at them all.

I see nothing wrong with the RTC being set to local time, and if someone 
installes Linux then Windows there is no way the installer can allow for 
the presense of Windows.
