I have done multi booting in a place that has summer and winter 
time. Windows has liked to keep the hardware clock in local 
time, so twice a year, it changes the hardware clock by an hour. 
If one multi boots N such operating systems, then the hardware 
clock is advanced by N hours in the spring, and retarded by N 
hours in the fall. 

My solution was to always have the hardware clock in GMT (UTC) 
for all operating systems and keep all the operating systems 
from adjusting it seasonally. For Windows, I told it that it was 
in Casablanca Morroco, because the clocks there at not changed 
seasonally, whereas London suffers from summer time. 

Remember the utc option for mounting FAT partitions.
