Discussion

When Type is SSType.Beginning, DateTime represents the date and time that ChangeTracking entries begin in the file. The Inserts, Updates, Deletes, and Ulinks values are always zero. There can only be one Beginning per set of snapshots.

When Type is SSType.Snapshot, DateTime represents the date and time the snapshot was applied to the file, and Inserts, Updates, Deletes, and Ulinks indicate the number of entries applied between the previous snapshot and DateTime.

When Type is SSType.Ending, DateTime represents the date and time of the inquiry, and Inserts, Updates, Deletes, and Ulinks indicate the number of entries made between the previous snapshot and the current time. There can only be one Ending per set of snapshots.
