Time zone doesn't change
In Date & time prefs, I checked the "set time zone automatically using current location." Therefore, when I drive from one time zone to another, I expect the machine's time zone to change. It doesn't. To get it to change, I have to enter Date & Time preferences. Then it changes by itself. What gives? I have repaired permissions. Thank you
