The file in question is /ect/defaults/rc
S. That small difference means a totally different file in linux terms.
Some theory so as you understand what you are going to do and how.
Windows assumes the bios clock is in local time. Linux on the other hand assumes it is on UTC, so it adds/substracts some hours so as to get its clock to your local time.
This behavior is controlled by the UTC=yes/no parameter in /ect/defaults/rcS. Set it to no and linux assume the bios clock is on local time, so no change when you reboot to windows and the opposite
On windows this setting is somewhere inside the registry.
