6. Change Date and Time Manually on Mac
If none of the above mentioned methods helped you fix your MacBook displaying incorrect date and time, you only have one option - manually set the date and time.
However, manually adjusting the date and time on your Mac has a few drawbacks. First, your date and time won't adjust automatically if you travel. If you're in a place that uses daylight saving time, your Mac's clock won't adjust automatically.
But considering that none of the automatic options helped you, this is the last and best way to fix the wrong date and time on your Mac.
Step 1 : Click the Apple menu and select System Preferences from the drop-down menu.
Click on the Apple menu.
Step 2: Go to the General section and select the Date & Time option.

This should temporarily fix the date and time issue on your Mac. However, it is best to set it to update automatically in the long term. So, try turning on the “Set date and time automatically” option to see if the issue is resolved.
If the issue persists, try restarting your Mac, updating it to the latest version of macOS, or try Secure Boot to see if any third-party software is causing this unlikely error. If all else fails, contact Apple Support to resolve the issue.
