I have a problem with the menu bar clock showing the wrong time after resuming from sleep. This doesn't happen a lot but when it does, I have to restart to fix it.

I have checked that my timezone is still correct (Eastern), the time shown in the Date & Time app is right and time syncs with apple servers - shown in the screenshot below.

Why is this happening? How can I fix the menu bar clock without restarting?

MacOS Mojave v10.14.5 (18F132)

    What is the version of macOS that you are running?

    If you are not on the latest public release of your version of macOS, updating it would be advisable, as this could be due to a bug in macOS.

I know you asked about a fix without restarting, but I really think your best option is to reset the NVRAM which, of course, requires you to restart your Mac. The reason for this is that your Mac's Non-Volatile RAM stores its timezone information.

Reset your NVRAM

To reset the NVRAM you'll need to follow these steps:

  1. Fully shut down your Mac
  2. Press the power button and then press the commandoptionpr keys. You have to make sure you press these keys before the gray screen appears or it won’t work.
  3. Hold those keys down for about 20 seconds (or until you know for sure your Mac has rebooted a second time)

  4. Let go of the keys and let your Mac reboot normally.

  • @samh Thanks for the feedback - I've added a couple of sentences at the beginning of my answer to address why I'm suggesting this, despite having to do a restart. If resetting the NVRAM works, then the problem won’t reappear and they won’t need to worry about it again, restarting or otherwise.
