IMac clock out of sync

So, since updating to Mavericks, I've noticed 2 issues.
First is the clock goes out of sync by about 5 minutes each day. I'm comparing it with my iPhone 5 and I know it's right as the iMac drops back to the correct time when I update from Date & Time in System Preferences.
Second is an issue with the switch user cube thing. I don't have Guest User on and it does this weird thing where it'll rotate the Desktop when updating things like AirPort Extreme settings from AirPort Utility and just now I updated VLC and it did the same thing. When it did it with AirPort Utlity the first time, it didn't switch back and I had to lock the screen and wake it up for it to display the Desktop again. Just showed a blank, white screen with nothing on it but the mouse cursor...
I have reset my PRAM yet for the clock issue but I believe it's software related as I've not had any issues prior to installing Mavericks.
Everything else seems to be okay other than some icons on the Desktop not showing previews for images or videos.
Anyone else experienced something similar? I know there's an update due shortly so hopefully that'll fix the problems...

Please read this whole message before doing anything.
This procedure is a test, not a solution. Don’t be disappointed when you find that nothing has changed after you complete it.
Step 1
The purpose of this step is to determine whether the problem is localized to your user account.
Enable guest logins* and log in as Guest. Don't use the Safari-only “Guest User” login created by “Find My Mac.”
While logged in as Guest, you won’t have access to any of your personal files or settings. Applications will behave as if you were running them for the first time. Don’t be alarmed by this; it’s normal. If you need any passwords or other personal data in order to complete the test, memorize, print, or write them down before you begin.
Test while logged in as Guest. Same problem?
After testing, log out of the guest account and, in your own account, disable it if you wish. Any files you created in the guest account will be deleted automatically when you log out of it.
*Note: If you’ve activated “Find My Mac” or FileVault, then you can’t enable the Guest account. The “Guest User” login created by “Find My Mac” is not the same. Create a new account in which to test, and delete it, including its home folder, after testing.
Step 2
The purpose of this step is to determine whether the problem is caused by third-party system modifications that load automatically at startup or login, by a peripheral device, by a font conflict, or by corruption of certain system caches.
Disconnect all wired peripherals except those needed for the test, and remove all aftermarket expansion cards. Boot in safe mode and log in to the account with the problem. Note: If FileVault is enabled on some models, or if a firmware password is set, or if the boot volume is a software RAID, you can’t do this. Ask for further instructions.
Safe mode is much slower to boot and run than normal, and some things won’t work at all, including sound output and Wi-Fi on certain models. The next normal boot may also be somewhat slow.
The login screen appears even if you usually log in automatically. You must know your login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin.
Test while in safe mode. Same problem?
After testing, reboot as usual (i.e., not in safe mode) and verify that you still have the problem. Post the results of steps 1 and 2.

Heartbeat time outs some times caused by clocks-out-of-sync?

Heartbeat timeouts are usually caused by the java socket communication between the master and its slaves being slow (or dead).
This slowness in turn can be caused by a system being overloaded, something than can easily happen when we're running out of memory.
Memory problems can be caused by running against file system cache, which in turns eats up all memory, etc.
Some times the java socket connection between the master and remote hosts just is slow, also causing heartbeat timeouts.
Today I had a case where, in a multi-host situation, one of the remote hosts had his clock set five minutes early.
On the master this resulted in lots of 'slow getmessage' warnings telling you that it took longer than five seconds between the time the message was sent and that it was received. These timings use both the master and the remote host's current clock values.
In above case that always meant that every message was considered five minutes late.
Then, further on during the test the remote system's clock was reset and increased by five minutes.
That was it for the heartbeat timer, because it also uses the system's clock values.
So, if you run into heartbeat problems again, check your clocks.
In your 'xxxx-0.stdout.html' file you can verify, within reason, the clock settings, for instance:
11:52:19.013 11:47:17.605 task_run_all(): 395 tasks
11:57:39.004 11:57:39.000 Slow getMessage: hd2-0 1957 301404 REQUEST_SLAVE_STATISTICS
The first time value is the timestamp from the master at the time the message was received, the second is from the slave at the time that the message was sent, and as you can see, there is a five minute difference. The next message shows the now changed clock values.
The important message of this: make sure your clocks are synchronized in a multi-host environment.

Clock out of sync when roaming

I went abroad for a few weeks and the clock never synced with network time. Because of that, the time was never correct and could gain upto 2 minutes each time I rebooted. I have an O2 Pre at version 1.4.1.

Hello and welcome to the forums;
When roaming, you can turn off network time and if you run into a situation where your time is off, you can then manually set it.
There is also a homebrew app that can sync your device to internet time (much the same way most PCs update time) however as this is homebrew, we are unable to offer additional support for installation or how to use it. www.precentral.net will have all the information you need, and a great support community that can help with installation and troubleshooting if you choose that route.
Hope this helps,

Clock out of sync again

ok, the clock, i cant get it right.
using KDE, i cant seem to get my clock to display what i want. since the new deprecation for the timezones, i have had problems. i went through the entire tutorial a couple times, and have made manual adjustments to files, and clock alike.
my clock is still about 7 hrs behind, which is my timezone, PST (los angeles) -8GMT, with daylight savings time is -7GMT, or vice versa.
anybody have any foolproof suggestions?

the error i was referring to was the time being displayed incorrectly, i mispoke. i had it set at UTC, and with my timezone set to Los Angeles, it looks no different than when i set the HW clock to Los Angeles, and system clock to Los Angeles.
i guess i can go through it again.
ok, after entering this
grep ^HARDWARECLOCK /etc/rc.conf
hwclock --utc
HARDWARECLOCK="UTC"
grep ^TIMEZONE /etc/rc.conf
cp /usr/share/zoneinfo/America/Chicago /etc/localtime
this set my current time to 5 hours behind, and my UTC to -12 hours behind, this is probably because the time was wrong to begin with.
then using KDE i set the time to current, which is 1:44pm
now
hwclock --show
reflects 1:44pm
by now im a bit confused.
i thought HW clock, was my cmos, not arch.
# date
Mon Aug 1 13:46:47 CDT 2011
now next time i edit my cmos clock which i alter my systems over here regularly, i will have to remember that i just changed my lifetime format from localtime to UTC, and have to first figure out if daylight savings time is in effect, to see if Pacific time is -7 or -8 currently, then add that to my local time to get UTC time. see how confusing setting CMOS to UTC is....
ok, i will admit the above was sort of a rant and to highlight the problems one may run into...
now, back to square 1,
ok
# hwclock --show
displays
Mon 01 Aug 2011 01:50:57 PM CDT -0.172132 seconds
and
# date
displays
Mon Aug 1 13:52:03 CDT 2011
but since i have a timezone set, why is HW clock (aka cmos) displaying the same as my desktop clock, when i set the HW clock for UTC?

Clock out of Sync

My clock is behaving erratically. Noticed it was almost two hours fast even though it's set to automatic/
24 hr New York Time Zone. Any ideas?

Turn on airplane mode then turn back off (force a new handshake with towers). This can happen at times if a tower (but more likely a repeater in tall building enviroment) has it's clocks off. Your time gets set from a tower (or repeater) upon handshake (after having no signal, won't happen during hand off I believe)

Audio Tracks and Video Out of Sync!!

I am having a problem with not only the video and audio being out of sync, but the audio tracks, left and right, are out of sync with each other. I know it isn't the camera or tape because I watch the footage while it's capturing and it is fine, plus it happens all the time, with different tapes and different cameras. What would cause this and how do I fix it? Also, how do I set my preferences to automatically start the camera when I click capture? I have it set on my iMac but I can't find it on my G5.

Video's audio out of Sync once imported to Encore CS6

Hello Everyone,
I'm having some issues with Encore CS6 on my iMac running OS X 10.9.5.
I'm trying to burn some video that i've captured off of VHS using Elgato Video Capture. It outouts the files as .mp4
The videos play fine outside, but as soon as I import them into Encore the audio becomes out of sync. I've burned many VHS to DVD's and for some reason the problem seems to be recent. There out of sync in the timeline, preview, and once burned.
I even tried using Adobe media encoder to convert the .mp4 to MPEG-2 outside of Encore and the audio was still out of sync. I even tried cutting a bit of the audio off at the front because it seem to be just a little slower, and it worked for the first 5 minutes then it became un-synced again.
Does anyone have any idea's as to whats going on? Or has experienced this problem?
Thanks,
Angela

Hi Stan,
Unfortunately it wouldn't let me selected the tree view. I did find a text view that has way more information. As for the length of the Audio and Video lengths there both 1h 23mn.
And below is for the MPEG-2
Thanks for all your help!

Audio and video out of sync after capture from Canon

Help for a newbie please? I have a Canon XHA1S and have a problem after capturing HD video. After capturing a 40 minute clip, the audio and video are out of sync. Seems like there is about a 3 second difference. The entire clip is like that in the source window; I made a couple of quick edits and have the same problem in the program window. Tried exiting and re-opening PP, but that didn't help. I'm running PP in CS6 on an iMac 3.4 GHz i7 with 8G of ram. Thanks!

I have NOT used it, but many say to try this for HDV capture http://strony.aster.pl/paviko/hdvsplit.htm

Audio goes out of sync when i open project on diff macs

i have an iMovie project created on an iMac saved to an external.
I go to open the project up on my macbook and the audio is out of sync.
I go back to my iMac with the same project and it works just fine.
I'm a bit confused because both macs use Mac OS X 10.6.4 and iMovie 8.0.6
what other differences might there be?
any input is appreciated as I'd love to work on projects while out in the field!

Try exporting the iMovie project as a single full quality dv format quicktime file.
I use iMovie6 HD and this is my usual procedure that works well.
Make the movie in iMovie, will involve many separate clips. When finished, export (share) as a single full quality dv format quick time file. When I have an hours worth of smaller projects, I create a new iMovie project and import all of the quicktime .dv files for each separate short project. I add chapter markers in this project, then share with iDVD. I then burn an hours worth of stuff at best quality and distribute to family and friends.
iDVD seems to work better with iMovie source that has fewer clips.
BTW: Are you having problems with standard def or hi def iMovie source. Another part of my procedure is that I take the raw tapes and download the entire thing into one iMovie project. I don't edit or change the footage at all, just want to archive to DVD for posterity. In this case, I want to share the iMovie project with iDVD directly. This has worked OK for standard def projects, but my first hi def project (1080i) that I tried, the sound was out of sync. To fix this, I had to create a regular DV widescreen iMovie project, and drag all the clips into it from the HD project. It took over an hour for my humble mac mini to convert the files, but I was then able to share with iDVD and the finished DVD worked ok.
Hope this helps.

Front Row on Snow Leopard has audio out of sync on movies and TV shows and some movies wont show images.

I have an iMac Core Duo 2GHz (yes, first Intel iMac). I have Snow Leopard v10.6.8 (latest/last MacOS version I could load) with the most recent Security Update (2013-003).
I have two issues with Front Row:
• Some of the movie files will not show the images, but I can hear the audio.
• On other movies and TV shows they start fine, but within a few minutes the audio is out of sync with the images, running about 3-5 seconds ahead... Looks like a bad dub of a Japanese movie from the 60s.
Now, I know it's related to Front Row, because when I jump over to iTunes and start the same movie or TV show it begins where I left off in Front Row, but images are fine and audio is suddenly in-sync.
However, with Snow Leopard being 2 major upgrades back - 3 if you count the upcoming Mavericks release - I doubt this registers as a "brouhaha" on Apple's radar screens. Then, again, maybe the spirit of Steve won't tolerate this Microsoft-like quirk, even if my iMac is still chugging along after 7 years and multiple MacOS X upgrades & updates...

I think I found my answer... or culprit. It has to do with Snow Leopard, and my iMac Core Duo, being the last of the dying breed of 32-bit systems, and that iTunes v11.x is 64-bit (heavily, at least)...
Guess I need to break down and replace my 7 year old iMac, even though it still works beautifully (otherwise).

Photo Booth audio and video out of sync

Hi everyone.
I tried recording a video three times today on Photobooth, and every time, the audio and video are out of sync. Does anyone have any solutions as to how I can fix this? Its ever since I downloaded Mountain Lion.
Thankyou.

HI, Jay Rhymes,
I'm having the same problem and took your advice.
Strangely, the first video I recorded in Photobooth after I changed the settings did sync audio and video.
But then I deleted that test and tried another, and it was a little off.
I deleted that test and tried a third time, and it was way off.
So if I close Photobooth and open it, the first video will apparently sync fine but subsequent ones won't.
Anyone else having this strange difficulty?

IPhone photos not seen in iPhoto - iPhone and iPhoto out of sync

Normally when I connect my iPhone 3Gs to my iMac, iPhoto '08 opens and my iPhone is recognized and all photos on the phone are shown in iPhoto, ready for import. However, my iPhone and iPhoto now seem out of sync. Without my iPhone connected, I opened iPhoto and it shows my iPhone in the device list; instead of showing photo thumbnails on my iPhone, iPhoto displays empty boxes where the photos would ordinarily be. When I connect the iPhone, iPhoto continues to show the empty boxes, rather than the photos on my phone. When I try to import one of the "invisible" photos, I get an iPhoto error message: "The following file could not be imported. (The import failed.)" How can I correct this behavior so that I can import iPhone photos again?

Try trash the following file
com.apple.ImageCaptureNotifications.DeviceDiscoveryDatabase.501
from HD/Library/ Caches
and restart your mac.

Captured audio is out of sync

I captured a 12 minutes clip using Capture Now in FCE 3.5 from my PAL camcorder Canon MVX4i (=Optura 600).
This is the first time it happens to me: the captured clip has the audio portion out of sync with respect to the video by 5 frames. So, the audio is consistently 5/25 fps = 0.2 seconds late during the whole clip. Unfortunately, this is quite visible when people are speaking.
As a workaround I set the clip in the timeline, unlinked the audio, shifted the video portion forward by 5 frames, marked the clip in sync and relinked (BTW it took me a while to find out that 5 was the right value: lot of tests adding and subtracting a frame at the time, and listening ...)
I doubt the cause is the camera, so my question is: what is the cause of this out of sync ?
Thanks
Piero
Some additional info.
I used the same setup I've been using so far: camera directly connected to the iMac, capture to an external firewire hard drive, use of Capture Now just because it's faster with short movies. Tha movie was shot with 16 bit audio. The shift is the same all along the clip.

Hi Ian,
I'll check tonight once more, just to be sure. I doubt though, because being aware of the possible impact of the 32KHz, I am usually careful. But I also know that editing after 11 pm is not recommended to me... I might do silly mistakes...
In any case, I'm afraid there is a problem with the tape. Could a damaged tape causes out of sync during capture ?
Thanks
Piero

All of my audio is out of sync:(

Hey,
Everything was fine now all my audio is out of sync. Anyone know why? The delay is about 1.2 second or so but is quite noticeable. Can this be fixed in Soundtrack?
Chris

thanks for the follow up. Anyone searchinf for iMac and FCP issues will find your thread. It's important and helpful because I don't know anyone around here who could have even GUESSED to change an iMac to AV mode. Never used FCP on such a machine.
