How to Fix macOS Sonoma Clock Bug and Shows Wrong Time After Restart
So, here are some fixes that will help you resolve the macOS Sonoma Clock Bug and Shows Wrong Time After Restart issue:
Fix 1: Restart the MacBook
Many minor problems can be solved with a simple restart, such as the device showing the wrong date, time, or location. Therefore, we recommend restarting your Mac before making significant adjustments to fix the macOS Sonoma Time Bug. Here are the simple steps you need to follow to restart your Mac.
- In the top left corner of the desktop, click the Apple logo.
- From the drop-down menu, select restart.
- Let your MacBook restart. You may need to wait a few minutes for the date and time settings to be updated.
Fix 2: Set Auto Date and Time
MacOS Sonoma Time Bugs can sometimes be resolved by toggling the auto time and date settings. Time synchronization ensures that your Mac is always at the correct time. To enable auto time and date, follow these steps:
- Navigate to General > Date & Time in System Preferences.
- Select “Set Time and Date Automatically” and toggle it on.
- In order to refresh the settings, disable the option, then re-enable it.
- Verify that the incorrect time issue has been resolved.
Fix 3: Set BIOS Hardware Clock
It is possible that a misconfigured BIOS hardware clock is to blame for the macOS Sonoma Time Bug. Keeping the system time is the responsibility of Basic Input and Output System (BIOS). Follow these steps to ensure the BIOS clock is accurate:
- You need to shut down your Mac running macOS Sonoma.
- Hold down the Command, Option, O, and F keys simultaneously while pressing the power button.
- When the startup chime sounds, release the keys. In BIOS mode, your Mac will now boot.
- To access the Terminal, navigate to the Utility menu.
- To disable network time detection, enter the following command in the Terminal:
sudo systemsetup -setusingnetworktime off
- Next, list the available time zones by entering the command:
systemsetup -listtimezones
- Make sure that you select the correct time zone by replacing the [Your chosen timezone here] with your selection):
sudo systemsetup -settimezone [Your chosen timezone here]
- Using the following format, manually set the correct date and time:
date -u [month][day][hour][minute][year]
- As an example, if November 30, 2023, at 07:18, the command would be:
date -u 1130071823
Fix 4: Manually Set Date and Time
Occasionally, manually setting the time and date is the best solution if all automatic options fail. Nevertheless, this method is not without its drawbacks. When your manual settings are out of sync with the real-time and date, they won’t be automatically corrected. There may be times when a problem occurs, in which case you will have to manually correct it.
It is also important to remember to change your settings before crossing borders into different regions. You will also end up living an hour behind or ahead of everyone if you live in a location that uses daylight saving time. Nevertheless, manual adjustments may be the best option if the automatic options don’t work and you do not wish to perform additional troubleshooting.
- In macOS, you can manually set the time and date as follows:
- Choose General > Date & Time from System Preferences.
- Turn off the toggle next to “Set Time and Date Automatically.”
- The manual date and time settings can be found at the bottom of the page.
- Your local time should be used to set the date and time.
- Verify that the incorrect time is now correctly displayed after saving the settings.
Fix 5: Remove Time Preference File
The macOS Sonoma Time Bug issue has been attributed to a corrupted date time preference file, according to several developers on Apple forums. MacOS reads this preference file whenever it restarts to determine the date and time preferences. This will result in an incorrect time on your computer if it is corrupted. It is necessary to remove this file from the system in order to allow it to create a new preference file automatically. To do this, follow these steps:
- Go to Mac preferences and choose General > date & time.
- In this case, disable the “set time and date automatically” feature.
- Afterward, on your Mac, open the Terminal app and type the following command:
/var/db/timed/com.apple.timed.plist ~/Desktop ; sudo reboot
- After that, you will be asked to reboot the system. In addition, you may receive a message stating that the command did not complete. Ignore this message.
- If you reboot your computer, you will have to reset the time and date settings to automatic.
Fix 6: Check Virus or Malware
According to many users, your macOS Sonoma Time Bug could be caused by virus infections or infected files. In many instances, viruses and malware on Mac OS systems alter the date and time settings on your Mac as a result of their actions. To make sure your Mac is safe, we recommend running an anti-virus and anti-malware program.
Fix 7: Downgrade MacOS
There appears to be a common issue reported by many users, which suggests a problem with the operating system itself. Mac OS Sonoma Time Bugs can often be fixed manually, but this is rarely a good option. I suggest downgrading to macOS Ventura if you aren’t concerned about the latest features of Mac OS Sonoma.
Fix 8: Contact Apple Care
For those who cannot resolve the issue with the above methods, it’s best to seek assistance from Apple care professionals. If they find any problems with your Mac software or hardware that might be causing the macOS Sonoma Time Bug, they will fix them, or they will help you downgrade to a MacOS version without the issue.
