Timezones are west of Greenwich.  If a zone is east (as Amsterdam is),
the difference thus is negative.  You add an hour, and specify -1.

I cannot comment on timezone issues on windows; not enough experience.
One hunch though: According to
http://oss.oetiker.ch/mrtg/doc/mrtg-reference.en.html you can set
'pngdate'. See if this is the correct time.  If it is, mrtg is not
able to set a timezone for its own process, but can set a timezone
for its children.  If so: try a batch file, setting the correct timezone,
and then calling mrtg (without a timezone parameter in its config).

I also have some doubt about that "-2". Are you expected to change
this parameter yourself whenever daylight saving changes?
