Observing my cellphone switch towers
At this one industrial customer I visit every week for a full day, my Verizon cell phone date/time time will suddenly change back by 19 years, six months, and some days (I don't have the exact value).  This has been going on for almost a year. My pet theory was that law enforcement turned on a stingray nearby back in 2020, it came up with a default date of 1/1/2001, and has been running ever since.  Steel building with warehouse plus office space. No one in the building is running one of those cell phone boosters that plug into customer internet and act as a mini tower. My newish pixel 4 and my previous Moto phone both demonstrate the problem.  I don't have the fortitude to call Verizon and work through support to get to someone who would understand the problem.  Has this happened to anyone else?  Any other theories on what it is?  (My workaround is to turn off updating date and time from the network)
