Mac OS time / clock error

I am running Sequoia 15.0.1 and have been experiencing errors with my Mac OS clock for months. Strangely the clock seems to be running slow, losing about 30 mins every 6 hours, like an analog clock. I have tried turning on and off Auto Time and Date setting, same with the Auto Time Zone setting. The system clock ends up being wrong with these toggles turned on or off. Manually setting location and time leads to the wrong time and date.

I have tried running Terminal commands that have been suggested by various people e.g. sudo rm /var/db/timed/com.apple.timed.plist

Not sure what else I can do!

You can re-sync to Apples time server from Terminal.app copy and paste:

sudo sntp -sS time.apple.com

(Please note: your psswd will not echo, type it in anyway, to proceed use the enter/return key)

Sonoma had some bug introduced early on that was sorted with point update.

Have not heard an issue with Sequoia here...

You can Set the preferences manually, no harm there—the option is toggle OFF "Automatically." I would do what works.

or from the Terminal.app copy & paste:

sudo rm /var/db/timed/com.apple.timed.plist

verify your software is up to date…

The current stable release of Sequoia including bug fixes, security updates is macOS 15.1

How can one accurately sync multiple Mac’s time without being connected to the internet?

You would have to set up a local time server, then have all the Macs connect to its address in System Settings > Date & Time > Source. No, I don't know how to create a local time server.

See if this helps...

Have you tried to update to macOS Sequoia 15.1?

Without any connection to the internet, the Mac has no way to get the correct time automatically. Without a connection, you would have to set the time manually (from a reliable source) but it would drift eventually.

I have also experienced this problems on Sequoia 15.0 - very annoying actually. Normally when I open my computer, then the clock is the same as when I closed the computer. I'm considering updating to see if the problem persists.

After running this Terminal command, you need to reboot your Mac. Also, consider upgrading to macOS Sequoia 15.1.
