Yes, chrony does use a different algorithm to discipline the clock. And
a standard has no business to specify how a program achieves the goals. 
It certainly has a business to specify what how the packets are
structured, and perhaps even suggest what standards it should achieve in
disciplining the clock, but how it does that should be no business of
the standard. 
It would be like saying that all editors should only use ASCII.
