iTunes and Your Time Zone

I wanted to post a solution that Pablo told me regarding fixing the iTunes backup problems. Pablo found that when he changed his time zone (he didn’t mention what he changed it to), the sync and backup problems were fixed.  This is what Pablo wrote:

To fix the “iTunes could not back up the iPhone because the backup session failed” bug found on itunes 9.2, you have to change your computer TIME ZONE and you will be able to backup witn no problems. This little trick fixed my two computers, one with XP and the other with Windows 7.

If this works for you, please let me know (post a comment) and thank Pablo for telling us about this.

    Just an additional information that may help others facing the same problem.
    I had this problem for some time and when I found this timezone tip I was able to finally backup my ipod touch.
    However, the next time I did a backup, the problem came back again. I tried again to change time zones but it did not worked… I tried a lot of different timezones, without success.
    Then I ran a Diagnostic Test in iTunes (go to Help > Run diagnostics)fot the the Device Sync. During the tests, the usual error came in. In the last screen, there is a summary of the test and I notice a line saying my Current local time was 23:45 when it was actually 20:43 in the clock in the system tray. So I changed one more time the timezone, from GMT-03 to GMT (that set my clock to 23:45, the same time reported by iTunes. Then I could backup with no problems.
    So… I am not sure if it helps or not but if changing the timezone randomically is not working, try matching with the time reported by itunes in the diagnostic. It worked for me…

    It works!! Thanks a lot.

    I want to know whats the logic behind this solution?

    Thanks again.

    I can’t believe Apple has a severe bug like this… since Ver.9…

    It solved the problem when i switched to GMT.
    I have itunes Ver.10
    Thank you for the help!

    This problem is unexplainable related to disabling “daylight saving time” option on Windows. On some countries, when daylight saving time starts and windows system clock do not adjust the system clock, a conflict appears with iphone backup and sync servers time, resulting on corefoundation.dll error.

    Changing the time zone to another without “daylight saving” option, or enabling this option, solves the problem.

    Hope it helps.

    Acho que você deve ser brasileiro, então vou responder em PT-BR: acho que seu problema continuou porque você provavelmente desligou também a opção “sincronizar automaticamente com um servidor de horário na internet”, ou utiliza algum que não o da própria Microsof ( Isso gerou um conflito entre o horário do syncserver e o horário do system clock do Windows.

    • Alexandre says:

      Valeu mesmo ! Deve ser isto. Eu estou viajando e não tenho como testar mas eu costumo deixar a opção desligada… Que bug FDP ! Valeu pela dica.

    Finally I was able to fix it and backed it up. Changed windows time zone from Central Time to Central America.

    Itunes was saving a backup file from 12-31-2000. Is this nuts are what?


    Thank you all!

    Interesting that this Apple bug still isn’t fixed after more then a year… I just had the same bug on my I-phone 4 when I tried to back up the Iphone. Problem started after both my computer and Iphone had automatically switched from summertime to wintertime 1 day ago. Changing the timezone on my computer to a similar timezone having the same actual time fixed the problem. Weird.
