      The current sign attribute of DV_DURATION should be
      replaced with a prefix "-" operation. The as_string feature also

      Description

      The sign attribute of DV_DURATION is incompatible with
      the normal way of representing negation of a quantity. It is not
      helpful in computations using durations. A prefix "-" operator
      should be defined to enable normal arithmetic to be used with
      DV_DURATIONs.
