Upload time is activity time

So I wanted create 365 days of fake data and upload it to Garmin connect.

I used java - created fit files.

I had to use Repair jar to upload it - files created by me doesn't work because they doesn't seems to contain all necessary info.

Every time that i upload it to webpage they don't preserve date - for example: Running activity is 18 September 2024 but on the website i see that i run on 24 November 2024 - upload date/ time.

Example csv 300 day file repaired:
