They are?  *Legally* traceable?  I've just read the first couple pages of Judah's
2941 PDF, and the things it says to me suggest that you cannot make that assertion 
*about the GPS system*, only about specific measurements it produces, and that 
distinction seems material in this context.

Are you missing it, or are you purposely ignoring what he said?

He is *not* "depending on [...] NTP".  He merely has to have it and log it
to comply with FINRA, or so his counsel tells him.

I'm declaring this part of the thread out-of-bounds for outages anyway; take it
to -discuss please, if you want to continue ignoring Matt.  :-)
