操作方法：发布具有首选时区的要素服务

摘要

As of ArcGIS Pro 2.7 and the December 2020 release of ArcGIS Online, it is possible to set a preferred time zone on a feature service with date fields. This alleviates the issue where date fields in a feature service appear in a different time zone when consumed in ArcGIS Pro compared to ArcGIS Online. 

过程

The preferred time zone must be set on the service after it is published. To do so, add the preferredTimeReference parameter in the service definition following the steps below:

1. Navigate to the updateDefinition operation at the feature service's admin endpoint. The URL is of the format:

https://<adminservicecatalog-url>/services/<serviceName>/FeatureServer/updateDefinition

• Note that you may need to append a token at the end of the URL

2. Remove everything from the text box
3. Copy and paste the following text to set the time zone for the service to Pacific Standard Time:

{ 
  "preferredTimeReference": { 
    "timeZone": "Pacific Standard Time", 
    "respectsDaylightSaving": true 
  } 
}

• To set the time zone to a different zone, use the appropriate "Name of Time Zone" string from the Microsoft Time Zone Index Values.

4. Click Update Layer Definition.
