Dear Tore, just for info. I had to do the correction myself after i changed the daylight-saving time to auto in Windows. That was simple, delete the complete track and thereby the race-definition i made myself. After re-uploading the track, adding Racenames, marks etc. again, all was fine, but also for another persons having the same problem with the same race.
The real problem is still in RaceQs. This timezone issue is only relevant for “international” races, but impacts also “local-time” races (e.g. club-races).
