I think you know, but just to be sure: PPCBoot does  not  know  about
timezones, so you must set the time in PPCBoot to UTC.

This depends on distribution and things like that.

No. Make sure /etc/localtime is  correct,  and  make  sure  the  boot
scripts  know  that  the  RTC  stores the time in UTC - under RedHat,
check that /etc/sysconfig/clock has a correct entry for  "ZONE",  and
that there is a line "UTC=true".

Hope this helps,

The software required `Windows 95 or better', so I installed Linux.
