  | 
  | *  now I change the timezone to Etc/GMT-2 (with raw offset of GMT-02:00)

  | --> now it's correct
  |   | 
  |   | 
  |   | Maybe it would also help to put a breakpoint somewhere into javax.faces.convert.DateTimeConverter to check when this method is called. But I do not quite know how to do that...
  |   | I suppose: the seam datetime converter extends javax.faces.convert.DateTimeConverter which must be somewhere in my JSF implementation: somewhere in the facelets.jar
  |   | but I have just could not find any DateTimeConverter class in the jsf-facelets.jar and I don't know where I can download the facelets source (yet..)
