All my activities are uploaded to Garmin Connect with the wrong time zone. It supposed to be Pacific Time. Instead, it keeps putting in Pitcairn Island Time. When the activities are synced to Strava, it is in the correct time zone. If I export the activity and import to Garmin Training Center or upload back to Garmin Connect, the time zone is correct. It has been going on ever since I got the watch back in July 2016. Very frustrating.
BTW, the device is Fenix 3. It is connected to my phone via Bluetooth.
