class Duration(Message[_DurationFields], DurationMixin):
    """
    A Duration represents a signed, fixed-length span of time represented
    as a count of seconds and fractions of seconds at nanosecond
    resolution. It is independent of any calendar and concepts like "day"
    or "month". It is related to Timestamp in that the difference between
    two Timestamp values is a Duration and it can be added or subtracted
    from a Timestamp. Range is approximately +-10,000 years.

    # Examples

    Example 1: Compute Duration from two Timestamps in pseudo code.

        Timestamp start = ...;
        Timestamp end = ...;
        Duration duration = ...;

        duration.seconds = end.seconds - start.seconds;
        duration.nanos = end.nanos - start.nanos;

        if (duration.seconds < 0 && duration.nanos > 0) {
          duration.seconds += 1;
          duration.nanos -= 1000000000;
        } else if (duration.seconds > 0 && duration.nanos < 0) {
          duration.seconds -= 1;
          duration.nanos += 1000000000;
        }

    Example 2: Compute Timestamp from Timestamp + Duration in pseudo code.

        Timestamp start = ...;
        Duration duration = ...;
        Timestamp end = ...;

        end.seconds = start.seconds + duration.seconds;
        end.nanos = start.nanos + duration.nanos;

        if (end.nanos < 0) {
          end.seconds -= 1;
          end.nanos += 1000000000;
        } else if (end.nanos >= 1000000000) {
          end.seconds += 1;
          end.nanos -= 1000000000;
        }

    Example 3: Compute Duration from datetime.timedelta in Python.

        td = datetime.timedelta(days=3, minutes=10)
        duration = Duration()
        duration.FromTimedelta(td)

    # JSON Mapping

    In JSON format, the Duration type is encoded as a string rather than an
    object, where the string ends in the suffix "s" (indicating seconds) and
    is preceded by the number of seconds, with nanoseconds expressed as
    fractional seconds. For example, 3 seconds with 0 nanoseconds should be
    encoded in JSON format as "3s", while 3 seconds and 1 nanosecond should
    be expressed in JSON format as "3.000000001s", and 3 seconds and 1
    microsecond should be expressed in JSON format as "3.000001s".


    ```proto
    message google.protobuf.Duration
    ```

    Attributes:
        seconds:
            Signed seconds of the span of time. Must be from -315,576,000,000
            to +315,576,000,000 inclusive. Note: these bounds are computed from:
            60 sec/min * 60 min/hr * 24 hr/day * 365.25 days/year * 10000 years

            ```proto
            int64 seconds = 1;
            ```
        nanos:
            Signed fractions of a second at nanosecond resolution of the span
            of time. Durations less than one second are represented with a 0
            `seconds` field and a positive or negative `nanos` field. For durations
            of one second or more, a non-zero value for the `nanos` field must be
            of the same sign as the `seconds` field. Must be from -999,999,999
            to +999,999,999 inclusive.
