normally, the CMOS clock is just used to set the system time when the 
system boots (or wakes up from sleep/hibernate), after that the time is 
maintained by the OS via timer interrupts.

my usual solution to time problems is to configure ntpd, but that may 
not be suitable for a laptop.

the tzdata is used for time zone offsets, daylight savings time 
computations, etc.   it should have no impact on the time of day 
maintained by the kernel.
