Slick!
However, it seemed that people who cared about time always wanted to
have their own NTP chimers which they owned and controlled. The
concern about relying on third-parties, and even the theorotical
NTP attacks.
A well-chosen set of sources obviates the need for this as well. NTP
is pretty good at spotting and ignoring martian sources.
