Is it possible to sync Bangle.js 2 time to smartphone time?

Does your script work indoors?

In my apartment and at work it also works indoor.

What sort of drift have you noticed so far between the two?
Approximately every 12 hours the difference increases to 2 seconds.

I reset my GPS chip to factory settings with

$PCAS10,3*1F

and still got a time within a second.
I think as long as there is a satelite in view, it will also find the time.
