And making it even less useful, only the absolute value of the measured (I say "measured" to distinguish it from "true") offset is being stored and graphed. This is somewhat useful if you truly believe that all offsets are randomly distributed between positive and negative numbers (and thus only the magnitude of the offset matters). But nobody who has been doing this for more than a day would believe this. It is a true reduction in the usefulness of the data to server maintainers that they cannot see the direction of the offset. This information would truly be useful to someone trying to diagnose refclock or asymmetric network delay issues.
