Also if your phone is set to use network time it uses Network Identity and Time
Zone https://en.wikipedia.org/wiki/NITZ messages from your mobile service
provider, which may not yet have been updated.
It is also possible some organizations or governments may deploy "Stingray"
2G/“Hailstorm” 4G/IMSI Catchers/cell site simulators (for tracking or
eavesdropping) which are not up to date, do not support the current time zone
settings, or provide correct time.
