some clues
- somebody else changes date too : find him ! might happen with some
cron'ed job calling some kind of time sync command
- you reboot and the system time is set from RTC which is not up to date
: compare system time to hardware clock ("date" vs "hwclock") eventually
set the h/w clock to the right time ("date --set" to set the system time
then "hwclock --systohc" to set rtc to the system time) -- another thing
is that the system assumes the h/w clock is running UTC but hwclock
actually doesn't -- another thing is you sometime boot another m$ os
with different time considerations
- the quartz is bad : check whether time lags quickly, for example every
hour you get 5 more (or less) minutes -- the system may though compute a
correct system time if the quartz is regular by handling drift
