Symptoms

Customer claims that the appliance does not maintain the proper time.

The offset below from the ntpq output is given in milliseconds, so the time is off by over 3 minutes from the 4 NTP servers.

Normally the reach would also be 377, which is an octal representation of the binary 11111111 - an eight bit value that gets set every time the appliance node successfully reaches the NTP server and sets the time.

Note that the ntpq command can be run from any unix/linux host and pointed to the appliance, so the customer can run it.
