 ### About work item revisions
 
- Each time you update a work item, the system creates a new revision and records this action in the `System.RevisedDate` field, which makes it useful for specifying a history filter. The revised date is represented by `RevisedDate` (DateTime) and `RevisedDateSK` (Int32) properties. For best performance, use the latter date surrogate key. It represents the date when a revision was created or it has null for active or incomplete revisions.
