      standard for representation of dates and times using the
      Gregorian calendar.  The profile is defined by the
      date-time production in Section 5.6 of RFC 3339.

      The date-and-time type is compatible with the dateTime XML
      schema type with the following notable exceptions:

      (a) The date-and-time type does not allow negative years.

      (b) The date-and-time time-offset -00:00 indicates an unknown
          time zone (see RFC 3339) while -00:00 and +00:00 and Z
          all represent the same time zone in dateTime.

      (c) The canonical format (see below) of data-and-time values
          differs from the canonical format used by the dateTime XML
          schema type, which requires all times to be in UTC using
          the time-offset ''''Z''''.

      This type is not equivalent to the DateAndTime textual
      convention of the SMIv2 since RFC 3339 uses a different
      separator between full-date and full-time and provides
      higher resolution of time-secfrac.

      The canonical format for date-and-time values with a known time
      zone uses a numeric time zone offset that is calculated using
      the device''''s configured known offset to UTC time.  A change of
      the device''''s offset to UTC time will cause date-and-time values
      to change accordingly.  Such changes might happen periodically
      in case a server follows automatically daylight saving time
      (DST) time zone offset changes.  The canonical format for
      date-and-time values with an unknown time zone (usually
      referring to the notion of local time) uses the time-offset
