gps issue

Is the set GPS time perhaps not registering in Bangle.js 2?

I'm not sure what you mean. By default, GPS time is now not used at all (but to be fair it was never used before unless your clock wasn't set).

If you want to actually update from GPS time then you'll need to modify the code you posted above so the checks like getFullYear()<2000 are removed, so time is always updated rather than only updating when the clock is obviously not set up
