       DESCRIPTION
           "This MIB module defines a MIB which provides mechanisms to
            schedule SNMP set operations periodically or at specific
            points in time."
       REVISION    "200201070000Z"
       DESCRIPTION
           "Revised version, published as RFC 3231.

            This revision introduces a new object type called
            schedTriggers.  Created new conformance and compliance
            statements that take care of the new schedTriggers object.

            Several clarifications have been added to remove ambiguities
            that were discovered and reported by implementors."

            schedInterval seconds have passed.

            The scheduler must ignore all periodic schedules that
            have a schedInterval value of 0.  A periodic schedule
            with a scheduling interval of 0 seconds will therefore
            never invoke an action.

            Implementations may be forced to delay invocations in the
            face of local constraints.  A scheduled management function
            should therefore not rely on the accuracy provided by the
            scheduler implementation.

            The first day of the month can therefore be specified
            by setting the bit d1(0) and d31(30) means the last
            day of a month with 31 days.

            Enumerations starting with the letter 'r' indicate a
            day in a month in reverse order, relative to the last
            day of a month.  The last day in the month can therefore
            be specified by setting the bit r1(31) and r31(61) means
            the first day of a month with 31 days.

            Setting multiple bits will include several days in the set
            of possible days for this schedule.  Setting all bits will

            Setting all bits starting with the letter 'd' or the
