Could it possibly be because the time is being set from GPS, somewhere in the stack? The 19-and-a-half year offset is spot on.

If so according to the link the phone needs to be from 2013 or older, or an iPhone from 2012 or before. That would give gp an award in no unnecessary upgrades :-)

I think they mean at the cellular network level (or stingray,) not the phone itself.

It could be a cell tower that gets its time from GPS (incorrectly)
