I need to persist Time Zone settings in Date/Time properites after cold boot on MC2180, WCE6.0.

I have put following lines in .reg file

REGEDIT4

[HKEY_LOCAL_MACHINE\Time Zones]
    @="W. Europe Standard Time"

but it looks like, you have to go to this setting and press OK (right button, on top of this screen) in order to "activate" this setting.

Otherwise my clock is +5 hours off.
Problem is that my Setting in TZ is set too GMT+1, Amsterdam, Berlin..., and showing it, but it looks like it's still on different TZ.
