Time displayed in my uploaded activities is the upload time and not the start time of the activity

[PhilippHofmann]

This activity was started at 10:12 and ended at 10:18 and the result was uploaded at 10:22 via API to Strava. How can I achieve that 10:12 is displayed on the Strava-Website instead of 10:22? start_date and start_date_local are set.

t was a wrong calculation of the UTC time and so the fit file contains time in future. It's solved after I have fixed this.
