Gets the time when the dependency was last changed.
Assembly: System.Web (in System.Web.dll)
This property is measured in Coordinated Universal Time (UTC) (also known as Greenwich Mean Time).
The following code example uses the AggregateCacheDependency class to add an item, with two CacheDependency object dependencies, to the Cache. When a request for the Cache item is made, the code checks whether the item is in the Cache. If it is, the property is converted to a string and displayed on the page. If it is not, the item and its two dependencies are created and added to the Cache.
