DDS — Ref-102 Addition_of time_related_constants

Open Closed All
  • Key: DDS-93
  • Legacy Issue Number: 6799
  • Status: closed

  • Summary:

    Sometimes it is necessary to represent a zero duration as well as an
    invalid time.

    A zero duration is needed for example to provide the value of a
    minimum_separation when a TIME_BASED_FILTER is not desired.

    An invalid time is needed when samples are returned that do not
    represent actual data.

    The representation of a DURATION_ZERO clearly is a Time_t with values

    {0, 0}

    . However it is desirable that the name of this constant is
    standardized across implementations.

    **PROPOSAL**

    Add the following constant to the IDL:

    Timestamp t DURATION_ZERO =

    { 0, 0 }
