Hi,
I created two Tasker scripts which help to rename GPX files to a more unified and timestamped form.
The script rnGPX analyses the gpx file and uses the first found trackpoint timestamp. It applies CEST corrections to that stamp! It uses and declutters the internally found name tag.
It automatically handles collisions (identical file names due to identical internal gpx names).
Backup is crucial here.
See below Reddit thread in the Tasker forum.
