MacOS – OS X timezone incorrect without internet connection

macos

After rebooting my macbook and my wifi is off, usually timezone changes randomly.

  • I tried to uncheck the "Set date and time automatically" option
  • Tried to uncheck the " Set time zone automatically "

Nothing helps, I want to set a default timezone/time to remember without internet connection

( can't really tell if its timezone-related but time/clock is always incorrect after boot without internet connection )

System Preferences shows this

Reset the PRAM, by holding the keys cmd-alt-P-R during startup. If the symprom does not go away, the PRAM battery is the culprit.
