Description

on creating a snapshot , we set modifcation time for the snapshot along with that we update modification time of snapshot created directory

  snapshotRoot.updateModificationTime(now, Snapshot.CURRENT_STATE_ID);
  s.getRoot().setModificationTime(now, Snapshot.CURRENT_STATE_ID); 

So on deleting snapshot , we should update the modification time for snapshot created directory .
