Since last update my Forerunner 235 doesn’t sync the date and time correctly. The clock shows the time which is 13 hours behind. Anyone else facing this problem?
Go outside. Stand under clear skies. Start (or just prep) a timed activity using an activity profile that uses GPS, and wait for a lock on the signal.
Automatically setting the time and date on the FR235 is by GPS (and I suggest you RTFM), and not the clock on your iPhone or your computer which cannot be regarded as trusted time servers or proxies for such, so syncing with either the Garmin Connect Mobile app or the Garmin Express application won't fix the time and date on your Garmin watch.
