Summary

This update contains time zone changes that were recently announced in Libya and Israel.

We recommend that you deploy the most current Windows cumulative time zone update (KB2779562) before installing this to guarantee the consistency of the time zone database on all systems.

Important
  • Before you apply the update that is described in this article, be aware of potential issues that may affect Microsoft Outlook. For more information about these issues, view the article in the Microsoft Knowledge Base:
    931667 How to address time zone changes by using the Time Zone Data Update Tool for Microsoft Office Outlook
  • Cumulative time zone updates contain only data that has changed for a specific region or that was added to maintain parity with other operating system versions. Therefore, if a time zone key is deleted, some original values may not be restored after you apply the cumulative zone update.

    Note We do not recommend that you delete any registry keys that are related to time zones. On a computer that has incomplete time zone keys, first restore the time zone keys from a known good backup. Then, apply the update.
