Yes, people get sloppy, but since we are on the ntpsec mailing list we
should prolly to stick to the NTP definitions.

According to ntp.org:

    http://www.ntp.org/ntpfaq/NTP-s-sw-clocks-quality.htm

    "The smallest possible increase of time the clock model allows is
    called resolution."

    "Precision is the random uncertainty of a measured value, expressed
    by the standard deviation or by a multiple of the standard
    deviation."

    "Accuracy is the closeness of the agreement between the result of a
    measurement and a true value of the measurand."
