When I imported a number of Zwift activities, I noticed a difference in date and time. Example: I had a Zwift session on 2017-11-21 20:45 CET. Xert imports this activity as 2017-11-22 06:45. I had set my timezone in Xert to CET before importing. This only happens with Zwift data, Garmin Edge data is imported correctly.
I tried to import/export the Zwift data via various channels - uploading the fit file from Zwift/activities directly, exporting TCX from Strava, exporting TCX from Golden Cheetah, exporting FIT from Trainingpeaks, etc. - always the same result. However, all the other systems (Trainingpeaks, Garmin Connect, Zwift, Strava, Golden Cheetah) show the correct date & time (2017-11-21 20:45CET).
Any idea how to fix this? Am I correct to assume that this is a cosmetic issue only?
