And all this time I thought cell phones were networked-synched for their time-of-day displays.
For the 10 years I've carried a cell phone (two qualcomms and now a Samsung), the time-of-day has been reliable and accurate.
That ended on Christmas eve day, when I temporarily lost my phone, decided to get a replacement (another Samsung) and discovered that its clock was 4-6 minutes slow. The T-mobile store people assured me this "happened all the time" -- some clocks were on, others were off. "That doesn't make any sense," I said.
They shrugged. My old phone was found and returned a few days later. I disliked the new phone for many reasons besides the slow clock, so I took it back, reactivated my old phone. And now it too was 4-6 minutes slow. I can travel to different areas and compare my phone to others' with the same carrier. They're on, I'm off.
I can manually set the clock in the phone, but within a few moments it is updated back to the wrong time. I went back to the store, checked maybe 18 display phones. Three were running 4-6 minutes slow, two were more than five hours off, the others were accurate, far as I could tell.
So now I'm trying to understand just how this is happening, assuming a network time sync signal, and moreover, how it can be fixed. (T-Mobile Tech Support said they wouldn't even consider generating a trouble ticket until "enough" people complained.)
Any ideas?
