Since I got my MiBand2 the time is behind by fife hours, at least consistently. Searching the issues tracker I found #441 but I think it’s not related, because my time offset is consistent.
I started with GB version 0.10.1 and now I am on version 0.15.0.
Firmware version was 126.96.36.199 till today, when I updated to 188.8.131.52, thanks to GB 0.15.0 :).
My timezone is UTC+01:00 at the time of writing its 12:20 but my band shows me 7:20.
During my initial setup the time was once correct. Due to some issues I did pair the band again and the time is of since then. Pairing again did not help. The time stays in sync though, just with the offset.
The activity graphs do show the activity at the right time though. The step counter on the band however is bound to the wrong time, thus starting over during the day.
Setting the time via the debug menu did not work, reconnecting and activating and deactivating the “sync time”-setting did not work either.
