Then, you need to check whether you have chosen the right time zone.
Check the Language & Region settings
If the region you have set is inconsistent with the one you locate, then such a conflict will lead to the clock error on Mac. Hence, you need to check and Language & Region settings on Mac, and change them if necessary. Just navigate to the Apple logo > System Preferences > Language & Region.
