I thought that multi-booting is good reason for preferring that 
the hardware clock be in UTC, so that when daylight savings time 
changes, that each OS doesn't redundantly advance/retard the 
hardware clock. On multi-boot systems, if one of those is 
MS Windows, I put MS Windows on UTC (Casablanca time?, 
because it doesn't have a summer time). 

What am I missing?
