# Set the Time Zone for Your Products and Promotions

The Catalog Product Relationship (CPR) determines the effective date and time. When you create a CPR record, you can set the `EffectiveDateTime` and `EndDateTime` fields in the CPR layout. The DateTime information you provide is based on your local time zone, as specified in your user profile. The system automatically converts your local `DateTime` to its GMT equivalent and stores it. This ensures that the `DateTime` information is consistent across different time zones.

**note:** This feature is available only to the classic Digital Commerce (DC) customers, and isn't extended to Standard DC or CPQ customers yet.

To enable and use the time-zone-aware date feature in CPR objects, follow these steps:

1. Set the Configuration:
   - From **Vlocity CMT Administration**, click **CPQ Configuration Setup**.
   - Update the ShouldConsiderUserLocaleforCPR Setting Value to `true` and save your changes.
2. Edit the Catalog Product Relationship Layout.
   - From Setup in Classic DC user interface, click the **Catalogs** tab
   - Select a catalog.
   - From the Catalog Product Relationships section, and click **Edit** on a CPR record.
   - From the quick access menu, select Edit Layout.
   - Add the Effective Date Time and End Date Time fields to the layout.
   - Remove Old Fields: Remove the Effective Date and End Date fields from the CPR layout.
3. Input Local Dates and Times: When creating or updating CPR records, use the Effective Date Time and End Date Time fields to input date and time in the user's local time zone.

**note:** If this feature is disabled, users cannot update `EffectiveDateTime__c` and `EndDateTime__c`. If enabled, users cannot update `EffectiveDate__c` and `EndDate__c`, as they are derived from `EffectiveDateTime__c` and `EndDateTime__c`.
