It looks like it is not able to adjust the extra hour as Amsterdam is now 
(with the rest of Europe) on summertime. If I only say 
TimeZone[device]:Amsterdam, it will display the time one hour off. However, 
if I say TimeZone[device]:UTC-2 the GRAPH with display the time correctly.
BUT: The text above the graph saying "The statistics were last updated...... 
" still refers to the time where the MRTG server is located and just adds 
"UTC-2" behind.

Do you know how I can do this?

I agree with you on this one, but I don't know how to get it the right way.
