Clock runs slow when I leave iMac on all the time

My clock has been running slow lately. Previously, I never had a problem. Two things changed, one of which is causing it:

1) I am now running Mavericks

2) I leave my computer turned on and set to never sleep the CPU so that I can mine cryptocurrency.

Yes, I have "Set date and time automatically" checkmarked (enabled). But when I notice my iMac's clock is off, I open Date & Time, then untick and then tick that checkbox, and then the time gets set correctly.

So something is preventing the date/time server from automatically updating my clock. It's currently set to Apple Asia because I am in Japan now. And I know that server works fine because, like I said, it works right away when I manually remove and then put back that check mark. But why is it not happening automatically?

Again, the only two things that have changes are that I am now running Mavericks and I leave my computer running (never sleeping) all the time.

Any ideas?

Thank you.

iMac, OS X Mavericks (10.9.1), March 2009 DuoCore, 8GB RAM, 1TB HD

I have had a similar problem, the clock was running slow on a Mavericks MacBook Pro I look after. After trying out several leads, one solution that worked was to change the value of the "Set date and time automatically" field in the System Preferences -> Date & Time -> "Date & Time" tab. Editing the text in the field from (in my case) "Apple Europe (time.euro.apple.com.)" to "time.euro.apple.com" fixed the problem for me.

It appears that the text in this field gets written almost verbatim into the /etc/ntp.conf file, which is then used to look up the time servers. Not only does "time.euro.apple.com." lead nowhere (due to the trailing "."), but Mavericks will even add "Apple" and "Europe" into the file. The end result is the time system appears unable to get a time fix, and so the clock time drifts, uncorrected.

If you are in Japan, you might want to try "time.asia.apple.com" in that field. The key thing is to avoid the trailing ".". Just change the text in the field an close window.

I should add that this wasn't the only step I took to debug my slow clock issue. Other steps included deleting and re-creating the /etc/ntp.conf file and exploring the "pacemaker" process. However, I don't think these steps were necessary in the end and simply adjusting the text in the field above should suffice. I could be wrong.

Needless to say you might have a different issue and this might not help. Good luck!

Thank you for the tip! I've just changed the text in Date & Time to time.asia.apple.com . I made no other changes. It usually takes 24-48 hours for me to notice a problem, so I will report back then as to whether your tip has solved the problem completely for me.

Well, it doesn't work. I found my iMac's clock running a couple minutes slow today, so I then opened the Date & Time panel in the System Preferences, only to find that my manually typed "time.asia.apple.com" had been replaced with "Apple Asia (time.asia.apple.com.)"!!!!

So perhaps your trick would work IF my changes would stick. But that isn't the case. (I am running 10.9.1, if that matters.)

I'm open to any other thoughts or suggestions.

Thanks.

If you are happy using the Terminal program, there are a few more things to try. Run Terminal, and try the following:

cat /etc/ntp.conf

(which should produce something like "server time.asia.apple.com").

Then try

cat /var/db/ntp.drift

(which should produce a number, e.g. -25.686)

cat /private/var/db/ntp.drift

(which should produce the same as above)

sudo /usr/libexec/pacemaker -v

(which should produce a running log of updates to the clock, e.g.:

Jan 29 07:45:17 Oxygen.local pacemaker[6142] <Info>: power status check: using external power

Jan 29 07:45:17 Oxygen.local pacemaker[6142] <Info>: created file monitor for /var/db/ntp.drift

Jan 29 07:45:17 Oxygen.local pacemaker[6142] <Info>: interval = 1 seconds, tolerance = 0.000000, drift = -25.686000

Jan 29 07:45:18 Oxygen.local pacemaker[6142] <Debug>: drift -25.686000 residue 0.000000 delta -25

Jan 29 07:45:19 Oxygen.local pacemaker[6142] <Debug>: drift -25.686000 residue -0.686000 delta -26

Jan 29 07:45:20 Oxygen.local pacemaker[6142] <Debug>: drift -25.686000 residue -0.372000 delta -26

Jan 29 07:45:21 Oxygen.local pacemaker[6142] <Debug>: drift -25.686000 residue -0.058000 delta -25

Jan 29 07:45:22 Oxygen.local pacemaker[6142] <Debug>: drift -25.686000 residue -0.744000 delta -26

Jan 29 07:45:23 Oxygen.local pacemaker[6142] <Debug>: drift -25.686000 residue -0.430000 delta -26

(the numbers and the computer name will be different)

If you could reply with the results of running those test, we might be able to determine if it's worth pursuing this line of attack (the next step might be to re-create the /etc/ntp.conf file and/or the ntp.drift file).

Hi there -

That's interesting. The fact that there is a "." at the end of the "server time.asia.apple.com." text in the /etc/ntp.conf file suggests this is worth pursing, because that appeared to be the problem before.

The other diagnostics seem also to be in line with the update not going through.

So, we can try to re-create the /etc/ntp.conf file as follows. Warning - this involves changing a system file, /etc/ntp.conf.

In Terminal, change to the Desktop:

cd Desktop

Make a directory to work in and avoid crashing into other files:

mkdir time-fix

Change directory to the new directory:

cd time-fix

Create a replacement ntp.conf file in that directory:

echo 'server time.asia.apple.com' > ntp.conf

And copy the current, "broken" ntp.conf file into this directory as a backup:

cp /etc/ntp.conf ntp.conf.backup

Finally, copy the new ntp.conf file into place:

sudo cp ntp.conf /etc/ntp.conf

Then, you could re-run the pacemaker test to see if the update is coming through:

sudo /usr/libexec/pacemaker -v

Depending on how it goes you might then want to either delete the "time-fix" directory on your desktop, or move the ntp.conf file back from the backup.

At this point, do I now just wait a couple days and see if my clock gets slow again?

Apologies, I should have added that you need to also restart the ntpd program so it re-reads the ntp.conf file that you just fixed. From Terminal again:

sudo killall ntpd

Then try

sudo /usr/libexec/pacemaker -v

again. When it's working, the rows of output from this last command should show a changing residue and delta.

Hi Tim,

Thank you for your continued assistance.

Here's what happened when I tried to follow your advice today.

1) Rebooted (with nothing set to auto relaunch)

2) Desktop appeared, Menubar appeared, but no Desktop icons or Dock. Spinning Pizza. Could click on and pull down menus, but couldn't choose anything. Waited patiently for 10 min. No change so I held down the power button until the Mac powered off.

3) Inserted my USB flash drive with Mavericks installer on it.

4) Powered on Mac and held Option key, then chose to boot from my USB flash drive.

5) Ran Disk Utility and Repaired Permissions first. It reparied Library/Printers/InstalledPrinters.plist and then it proceeded to repair just about every Resource imaginable in Applications/iBooks.app. After that finished I ran a REPAIR DISK, and then it finally gave me the Green OK, so I rebooted into my iMac's internal HD.

6) Desktop and icons appeared this time. Goodie!

7) Launched Outlook.

8) Launched Terminal and did the following:

James-iMac:time-fix james$ sudo /usr/libexec/pacemaker -v

Am I good to go now?

Or do I need to give it another couple days to see if the clock goes slow again?

Thanks.

It's been a few days.

My clock is back to being 5 minutes slow again.

Any further advice would be appreciated.

I've been following this and other related threads with lots of interest, as the clock of my unsupported Mac Pro 1,1->1,2 ran fast for a few days after installing Mavericks and then started running slow. I followed all the advice I could find, but, up to now, to no avail. Except for something I tried yesterday at noon (British time): I opened the Mountain Lion install media with Pacifist and installed the ML ntpd Unix executable on top of the one provided with Mavericks (in /usr/sbin). Ever since, the clock hasn't drifted. See if that solves the issue for you. It's the most promising solution for me so far. Good luck.

What specifically is this "ML ntpd Unix executable" and where specifically is it found inside the 10.8 installer when using Pacifist?

Thanks.

Ntpd stands for "Network Time Protocol daemon" and, as I said, it's a Unix executable. When you open any media with Pacifist, simply use its search function to locate what you want to install. In this case, enter "ntpd" (without quotes) in the search field and you'll be presented with a list of items whose name contains "ntpd". Select the one named just "ntpd" and copy it to /usr/sbin (hidden by default). If your case is like mine, your clock shouldn't drift anymore after rebooting once. If it works for you, let us know.
