I have tried it with --utc instead --localtime and /etc/default/rcS with
UTC=yes

It seems it works, but... I have always 2 hour of difference between
Windows and Linux. If I have Linux with the right time, then Windows is
2 hour behind. If I adjust Windows then Linux is 2 hour in advance.

I will spend a bit time with this issue later.

Thanks.
