This same problem showed up this week for my wife and me. We both have Samsung S8s. They are randomly switching to Pacific time, then back to the (correct) Mountain time. It's especially bad for my wife, since she has a Samsung Watch, that is synced with her phone. For now, I've set her phone to not use network time. I have a regular watch, so I'll let my phone wander for a while. This is in Arvada CO, about 5 miles west of Denver. Is this a flaky cell site?
