There appears to me to be a variety of outputs for each. I don't
have an opinion on which is "greater"

Extremely convoluted.  They would just use STCK/STCKF/STCKE then STCKCONV.

Most programming examples in the reference books do not show results. They 
are primarily intended to show you a way to invoke the service. This 
example does that. Examples may also show how to deal with the output data 
(but that seems unnecessary in this case).

>I might suggest as an alternative ....
In my opinion, it would not help anybody's understanding of the service to 
have a detailed example about leap seconds, because the specific date/time 
is unimportant to understanding use of the service. But if you think it 
important that a reader understand the lack of leap seconds processing, 
that's reasonable to describe.
