GPS Recorder: invalid Date of Track

Thanks! Well that's a surprise - so it all seems to be working fine on the Bangle - just for some reason the interface on the PC isn't understanding the received data.

I even copied the file contents I see in your dump and put them into files on a Bangle and ran the GPS recorder interface and it listed all the files for me!

But this did give me a thought. In the dev console, it should be possible to run a command like:

downloadTrack(21, track => saveGPX(track, `Bangle.js Track`));

To kick off the download manually - although it needs to be debugging the iframe at that point, so I wonder how you do that.
