By default, your Chromebook's time zone setting will be "Set automatically." When this is enabled, your Chromebook will use your IP address or a nearby network to find your approximate location and estimate your time zone. Because of this, the time may change if you're traveling or if you aren't connected to the internet.
To avoid this, you can set the time zone manually. This means your Chromebook's time zone will always stay the same, even if you travel to a different region or have no internet.
Under the Date and time tab in the Settings menu, select Time zone.
Select CONTINUE to visit HP's website.
