Installing time zone updates

When the laws and regulations governing time zones are changed, Microsoft releases time zone updates. This topic explains how to install a time zone update for Microsoft Dynamics AX.

Overview

A Microsoft Dynamics AX time zone update is released as an .XML file. The .XML file contains time zone definitions. A time zone definition represents a time zone and lists the properties of that time zone.

To better understand time zone updates, suppose a country or region changes its laws governing when Daylight Savings Time (DST) is observed. Microsoft will release a time zone update for Microsoft Dynamics AX that includes these changes. You should download the update and import the time zone definitions into your Microsoft Dynamics AX database.

After you import the time zone definitions, you must update your Microsoft Dynamics AX data based on these definitions. For example, you may need to update sales appointments or job schedules affected by the DST changes.

How to install a Microsoft Dynamics AX time zone update

To install a Microsoft Dynamics AX time zone update, complete the following procedures.

Verify that you have installed Windows time zone updates

Verify that you have installed time zone updates for the Windows operating systems used in your organization. To download and install Windows time zone updates, go to www.microsoft.com/time.

Download the Microsoft Dynamics AX time zone update

Microsoft Dynamics AX time zone updates are available on the CustomerSource Web site. A Microsoft Dynamics AX time zone update is released as an .XML file. Download the file and save it to the hard disk of your Microsoft Dynamics AX client computer.

Prepare to import time zone definitions

The .XML file that you downloaded contains time zone definitions. A time zone definition represents a time zone and lists the properties of that time zone. You must manually import the time zone definitions into your Microsoft Dynamics AX database.

Before importing the time zone definitions, complete the following tasks:

  • Instruct all users to log off Microsoft Dynamics AX.

    To determine if any users are logged on to Microsoft Dynamics AX, use the Online users form (Administration > Common Forms > Online users).

  • Make a backup of your Microsoft Dynamics AX database.

    For information about how to create a database backup, see the Microsoft SQL Server documentation or the Oracle Database documentation as appropriate.

Import time zone definitions

Complete the following procedure to import time zone definitions into the Microsoft Dynamics AX database.

  1. Open the Time Zone Import form. To open this form, do the following:

    • Open the Application Object Tree (AOT).

    • In the AOT, expand the Forms node.

    • Right-click TimezonePatchImport and select Open. The Time Zone Import form is displayed.

  2. In the File name field, enter or browse to the time zone update .XML file.

  3. Click Import.

    The time zone definitions that are specified in the .XML file are listed in the form and saved to the Microsoft Dynamics AX database. Complete the following procedure to update your Microsoft Dynamics AX data based on these time zone definitions.

    Note

    The Time Zone Import form lists all time zone definitions that have been imported into the Microsoft Dynamics AX database, including time zone definitions that may have been imported on previous occasions. The Patch Applied check box indicates whether Microsoft Dynamics AX data has been updated based on a specific time zone definition. If the Patch Applied check box is not selected for a particular time zone definition, use the following procedure to update Microsoft Dynamics AX data.


Update your data

Complete the following procedure to update your Microsoft Dynamics AX data based on the time zone definitions that were imported.

  1. Open the Time Zone Patching Tool form. To open this form, do the following:

    • Open the Application Object Tree (AOT).

    • In the AOT, expand the Forms node.

    • Right-click TimeZonePatcher and select Open. The Time Zone Patching Tool form is displayed. The top half of the form lists the time zone definitions that have been imported.

  2. Select a time zone definition that does not have the Patch Applied check box marked.

  3. Click Load All Affected UtcDateTime Fields. The fields that contain date and time values—that apply to the time zone definition you selected in the previous step—are displayed.

  4. Select the fields you want to update. We recommend that you update all fields.

  5. Click Apply patch.

  6. Repeat steps 2-5 for each time zone definition that does not have the Patch Applied check box marked.

Restart AOS servers

After importing the time zone definitions and updating your data, restart each AOS server.
