Time keeps changing.

Hello, I have a 13" MacBookPro5,5
And I started to have problems with the time.
SOMETIMES, when I turn on my mac, the time is 6hrs behind from what it should be.
So if it's suppose to be 7pm, it says 1pm!
The worst thing is that if I go to date and time preferences, the timezone is CST.
So, why then, if my settings have the right timezone is going back 6 hours?
I have to manually change my time.
But it doesn't last long,because after one or two reboots, I have to fix it again.
Anyone know what could be causing this?

Hi guys / gals,
have a look at http://www.keiths-place.com/blogs/keith/2007/gmt-timezone-problem-mac-os-x which describes a similar problem and provides full instructions for fixing it.
Another alternative approach, that seems to work for many, though, is outlined by Imacy at http://discussions.apple.com/message.jspa?messageID=8453075#84530755
Cheers

Time keeps changing on phone

iphone 5 keeps changing time. About 1/2 hour.

Check Settings > General > Date & Time >
Set Automatically: ON?
Time Zone > your city?
Try a
Reset: Hold down the Sleep/Wake button and the Home button at the same time for at least ten seconds, until the Apple logo appears. Note: You will not lose any data

Time keeps changing back two hours!

Ipod touch 4th gen. The time zone is set to Monterey (Tennessee). They have the same time as we do in Crossville. My Ipod keeps changing the time back two hours for some reason. So right now, its 9:26. My ipod says it's 7:26. I can change it back manually, but it just changes back. I didnt have this problem before i had to restore it from the update freeze. Is there another Monterey in the U.S.A. or is it just the ipod?
My computer (Toshiba Windows 7) does it too, but i dont remember if it did it before my ipod froze.
Please help!

I didnt think it was obvious. Everyone I asked always told me it was a different time zone. Well whatever, thanks.

IPhone Date & Time keeps changing to "Cupertino" time zone

Hi
Every time i change my Time Zone in Settings>General>Date & Time to "London,United Kingdom" it correctly changes to "London" but if i exit Settings and navigate back to Time Zone settings it has changed to "Cupertino".
This effects World Clocks and other apps which is most annoying.
I have firmware 2.0(5A345) installed on the iPhone. Is there a way to upgrade this? Will i lose all my current data if i do a firmware upgrade? Will it even fix the issue?
Please help, there are currently 2 options I have. Find a fix or move to Cupertino so that my iPhone displays the correct time.
Is there a less drastic option?
Thanks in advance!

If i do that it states that i am running the current version. Maybe because it is a revision and not a proper update.
My twin brother also has the the version that you have (54347).
Apparently it updates the firmware when you do a "Restore" through itunes but that will wipe the phone clean of everything. I don't mind doing this as long as i can transfer my backed-up content but if i do a "Restore from backup" to tranfer all my settings etc i have a feeling it will revert it back to the firmware that the iphone was running when it was backed up. Hope that makes sense!
Thanks

Time keeps changing whenever I sync my Ipod to my laptop (itunes)

The time in my iPod keeps on changing whenever I sync my device to itunes in my laptop. Can someone please help?

Hi guys, I have a iphone 3gs 16gb but nomatter how many times i set the time and time zone on my phone, when i next plug it into itunes 10 it knocks the clock 8 hours forward. I've even set the time on my ipone while connected to itunes rhen synced it, but the next time i connnect it it knocks it 8 hours forward again and again and again. The same thing happens when i turn on the auto function by the same amount of time, wether connected to itunes or not. My PC is set at the right time and zone and im more than frustrated with this problem. My wife has the exact same iphone as me and on the same network but does not have this issue and all our setting are the same just incase it was something i was doing wrong on mine but to no avail.
Please can someone give a definitive answer to this annoying problem

Miix 10 Time keeps changing & bluetooth stops

I frequently encounter with these two problems.
1. From time to time the system time changes arbitrary and seems like we are 2-4 days AFTER. For example, a while ago it showed that the current system time was 12:00 of Thursday, 27/02/2014 although it really was 23:00 of Sunday, 23/02/2014.
If I go to time settings and try to synchronise the time of the tablet to the Internet Time it restores the real time, but displays an error message.
2. From time to time the bluetooth connection between the tablet and the bluetooth keyboard and bluetooth mouse stops (they are both Microsoft Wedge). The Bluetooth settings disappear from the Settings menu and I have to set the tablet in flight mode and then to switch flight mode off for the bluetooth device to turn again on and reconnect with my two bluetooth devices. I tried to reinstall the bluetooth drivers, but the problem insists.

Hi barbershark,
welcome to macbook forum.
how bad was the time changed? is it back to 19xx years? ussually, it happen after resetting PRAM or when a mac run out of "CMOS" / flash memory battery, but on new macbook is highly unlikely.
do you have windows with bootcamp in your macbook, if you do, set and adjust the date, time and time zone as well on windows part.
it is recommended to adjust time automatically if you have internet connection and already set the time zone correctly.
also Reset PRAM:

Reset SMC/PMU:

Good Luck.

Clock time keeps changing by 12 hours

I have a 3rd Gen Touch that was my husband's before he got an iPhone. One day I noticed the calendar was showing the wrong day. On closer inspection, the problem was that the time was off by 12 hours. Instead of Wednesday 9 am it said Tuesday 9 pm. I went into Settings to fix it, making sure I had the AM/PM correct. Several days later I noticed it was off again.
Five days ago I corrected it again. Today, it is again off by 12 hours, telling me it is 4 am rather than 4 pm. This makes it pretty useless as an alarm! Any idea what's going on and how to fix it?

First, go to Settings > General > Date & Time and make sure you selected a time zone that is the same as the one you live in. Set the correct date and time.
Next, go the the date and time settings on your computer and make sure the correct time zone is selected and the clock is set properly. Sync your touch and make sure the times match.

Calendar and time keeps changing to 2015!

i have sprint. they are having tower issues but say this is not related. I have 3 iphone 4s' and 1 iphone4. all are affected. Can't text, make calls, use most apps (most important being square app for my businesses). Cant do anything. My ipad (not sprint issue) is not affected. I'm in the Eastern Panhandle of WV. Not many sprint users here so I have no one else to ask. Is any one else familiar with this problem? I am going back (again) to an apple store today if the sprint store can't help but I'm pretty confused. I should also mention that this same thing happened last week from Sunday til early wed am. This time it started late saturday. I'm pretty sure this is a sprint problem but don't know how to fix it. Suggesions?

Go to Settings>General>International and make sure that Calendar is set to Gregorian
and that ins Settings>General>Time and Date is set to Automatic
Next:
Try:
- Reset the iOS device. Nothing will be lost
Reset iOS device: Hold down the On/Off button and the Home button at the same time for at
least ten seconds, until the Apple logo appears.
- Unsync/delete all music and resync
To delete all music go to Settings>General>Usage>Storage>Music>Tap edit in upper right and then tap the minus sign by All Music
- Reset all settings
Go to Settings > General > Reset and tap Reset All Settings.
All your preferences and settings are reset. Information (such as contacts and calendars) and media (such as songs and videos) aren’t affected.
- Restore from backup. See:
iOS: Back up and restore your iOS device with iCloud or iTunes
- Restore to factory settings/new iOS device.

The time keeps changing on my iPhone 5C even though I've manually set it. Help!

I've been having trouble since yesterday where the screen was just black as if it was switched off. I couldnt unlock the phone or see the screen at all but I could only hear the phone when it rings but the screen remained black.

Hello LaylaAlHajeri,
It sounds like you the time is acting unexpectedly on your iPhone. I recommend starting by closing all the open apps on your device:
iOS: Force an app to close
http://support.apple.com/kb/ht5137
Double-click the Home button.
Swipe left or right until you have located the app you wish to close.
Swipe the app up to close it.
When you have done that and restart the phone and test the issue again:
iOS: Turning off and on (restarting) and resetting
http://support.apple.com/kb/ht1430
If it persists, I would next try the steps in the article named:
iOS: Troubleshooting issues with date and time
http://support.apple.com/kb/ts3920
Follow these steps. Test after each step to see if the issue is resolved.
Ensure that the version of iOS on your device is up to date.
If the option to enable date and time automatically is available, turn it on. Tap Settings > General > Date & Time.
Ensure that your time zone is set up correctly. Tap Settings > General > Date & Time > Time Zone.
If the incorrect date, time, or time zone is being set up automatically on the device, please notify your cellular provider. In the meantime, tap General > Date & Time and turn off Set Automatically. Then set the appropriate time and time zone manually.
Note: The option to set automatically might not be available on all carriers in all countries.
Additional Information
Note: If you find that your device's time is incorrect after you sync with your computer, your computer's time may be incorrect. Verify the computer's time in System Preferences > Date & Time (you may want to select the checkbox to set the computer's date and time automatically).
Thank you for using Apple Support Communities.
Regards,
Sterling

My MBP (retina) keeps changing the time!

I recently brought a new MBP with retina but the time keeps changing by its self! I have tried setting it to manual time but it still changes. I have also turnt off auto detect timezone to see if it was that but it still changes. I also use windows 7 on my mac if that helps.
Thanks Hayden

How are your Date & Time System Preferences set? Here's a snap of mine:
I'm not having any problems - I just allow the Apple Server to set the date and time with the correct Time Zone selected.

Last Played Date is wrong ...Ipod keeps changing date

I own a 3rd gen iPod nano and the date and time keeps changing everytime I connect it to my PC ...can anyone help me figure out how to fix this please...?
Thanks in Advance

Well, iPod sync the Time/Date from the Computer, you should check, if GMT+x is right ... and that should fix the problem.
Note: Your iPod should also be set to the right Time Zone ( Settings > Date & Time > Time Zone. )
Hope this helps,
Darie.

HT2513 my iCal calendar that I created with the color green keeps changing to purple. no matter how many times I change it to green, it turns it back to purple. Of course this only happens with iCloud and not "from my Mac". Any ideas?

my iCal calendar that I created with the color green keeps changing to purple. no matter how many times I change it to green, it turns it back to purple. Of course this only happens with iCloud and not "from my Mac". Any ideas on how to correct this? This seems like a trivial error, but it's super annoying.

I called Apple and they said that they know about this problem. It's a problem with iCloud which their Engineers know about. (there was a new iCloud release, hence...) No ETA for a fix yet. I asked that this be escalated so Engineering doesn't put it at the bottom of their fix list. I talked to a Senior Advisor and mentioned to them to have QA check their regression tests as this has happened before to me (the problem just didn't take this long to resolve). I like to use green too for important stuff, so I've resorted to creating a new calendar using the normal calendar green for events going forward. They could have picked another color besides green to have this problem with and I wouldn't have been so upset. ;-)

I've purchased cartoon tv shows for my iPad. Prior to the new updates, I could play one at a time or continous. Now I can only play one at a time. It's annoying to keep changing it every five or six minutes. Is there a fix to get it back playing continous
