Invalid track on Garmin Edge #36
Description
Garmin Edge 1030, Samsung Galaxy S24+, Locus 4
Hi Harald,
since a while I notice a weird phenomenon:
The procedure I follow since ages is to create tracks on Locus 4, export and beam them to Garmin Edge, always with the same settings.
Now, when sending the track to Garmin Edge, it first opens with no issues.
But when I store the track to "Gespeicherte Strecken" and try to open it again, I get the message "Ungültige Strecke".
It seems that this issue occurs since the last update on July 6.
I downloaded a GPX file from Quäldich.de which works without issues.
But according to Locus support, nothing has been changed regarding the xml scheme for gpx export.
I am clueless what might be the reason.
Do you have any idea?

The same track transferred via USB has no issues.

Found it: Locus writes route times relative to 1970-01-01, before the FIT epoch (1989). Up to 20.0 those times were not parsed at all, so the course had none; since 20.1.0 they were written as they are, and the Edge rejects the saved course. Fixed in #38: such times are moved to the FIT epoch, keeping the durations. Thanks for the sample file, it made this reproducible!

Thanks for drilling this down!
