Passport updating to US Central time instead of Mountain?

My girlfriends passport keeps updating to mountain and central back and fourth.

She's on AT&T unlocked of course. Is there anything to do besides just remove network time updates?

Thanks

You can set the Auto update time zone to "Prompt" or "Off" and keep the "set Date and Time Automatically" on.
I'd suggest "prompt" to try to figure out why/when she's dancing between these TZ ... (<= probably the mandatory diag before we can go further)

Hope it helps
