I can only confirm that the Android/Gadgetbridge TimeSync after connect works like a charm.
Personally, for me, it doesn't matter if the time difference is e.g. 5s per day.
I don't use a clock with seconds active
The clock reconnects 10 times during day and resync time (because the mobile lays somewhere on desk and i leave the BT radius -> resynced time after within raduis again)
If I would need to know the exact time I took a look at the mobile or some other ntp time-synced device
