Normally the time is read again in the startup scripts of the distribution.
Sounds like he configured the wrong time zone. Usually distributions
can be configured to assume UTC real clock time or local time RTC.

You can test that theory by commenting out any calls to hwclock
in your boot scripts. 

But that behaviour should be the same in all kernels.
