Your code has similar problems.  Right?

That's 1024 weeks after ntpsec is released.  I'm willing to assume that ntpsec 
gets updated more often than that.

We could add a config option to sepcify the pivot date but that doesn't seem 
worth the effort.  It would only be useful for cases where a modern ntpsec 
that couldn't be updated was being used with an old GPS unit.

Do we have any place to collect documentation for quirks like this?

These are my opinions.  I hate spam.
