Would this be a better commit message?
I'm using devices which have battery backed RTC. Sometime I need to use local
timezone for system time as for example CEST(UTC+2) timezone.
The problem is, that as soon as I enable CEST timezone for system time, the
battery backed RTC clock gets screwed with every graceful reboot as the
sysfixtime script writes system time to RTC in system's CEST timezone instead
in UTC. Linux kernel on next reboot expects time from RTC to be in UTC, but
the time is there already in CEST resulting in screwed clock.
