  // 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".
