You get the gold star for using ntpq as it was designed to be used :)
So many people screen-scrape human-readable ntpq displays without
realizing it's all built on var=value underneath.
And completely unsave ( and opaque to boot ) .
( Not that i refrain from using similar constructs on all occasions.
but I would prefer a "save eval" that works inside a limited namespace )
