Your assumption is that only people on the IDD use LDM; I would
challenge that perception, and argue that LDM is utilized outside of IDD
probably more than in it.
I would argue that putting any additional sanity checks in the LDM code
will have undesired results outside of the IDD paradigm.
And I'll argue that anywhere that uses LDM constitutes an IDD. If I
wanted to get pedantic, LDM is a publish-subscribe system. Pub/sub is
the basis for all sorts of time-sensitive transaction processing, like
the financial markets. I'm not suggesting LDM is used there, but the
pub/sub concept certainly is, and the last time I had a grad student
evaluate LDM for potential enhancement, that's the gold standard he and
LDM were held to in his committee.
I think I could support a sanity check for a decent NTP server, and
argue infavor of a server check. If not NIST, then to something that's
no worse than a Stratum 2 time server. I'd make it a big, ugly warning
(and not fail out), and see if we couldn't build some improved performance.
Time stamping on Level II data's been a problem since the first days it
was introduced in this current networking format. I hoped it'd get
better and have lobbied for the few additional checks it'd take, but
it's not gotten better.
