[evla-sw-discuss] NTP, EVLA MIB's and phase jumps

[James Robnett]

    The process of 'correcting' ntp is painfully slow so I
still don't know whether it's slewing in the proper direction.

    I'm beginning to see that andy (which is currently not
multicasting) is beginning to correct it's clock drift.  If the
correction is in the right direction it was *way* off before.

    500ppm (parts per million) is considered 'too much'.  With
the flawed kernel it had gotten up to 320, it's now down to
195 but I think the sign is still wrong.  IE it's still not
right but it's becoming wrong less slowly.

    I'm going to watch it for a bit longer and then restart
ntp and let it return to multicasting./

    I'm also going to apply the fix to amos right now.

    I don't *know* that this was the problem or that it fixes
it but early indications are that it does.
