That setting will not work well if you change zones, because there is no zone information in the cmos clock.
Think.
Europe. Cmos store local time. Fly to New York. Linux. You change the the time zone, not the clock: it is automatic. The changed hour goes to the cmos. Now you boot windows - but windows still thinks in European time, and is off by 6 hours. So you also have to change it. And when you change its time zone it will also change the time again.
As I understand, Windows 7 can use the cmos at utc. So I was told, I have to find the setting.

make sure SuSE is set to use local time *not* GMT. That is a must with dual-boot
boxes (or at least it was through vista). Win doesn't understand the hwclock set
to GMT so win will always be off by the tzoffset if you set Linux to use GMT.
Err, replace GMT with UTC above (although they are the same for all practical
purposes, or for that matter, 0 zulu)
