39/// A Duration represents a signed, fixed-length span of time represented
40/// as a count of seconds and fractions of seconds at nanosecond
41/// resolution. It is independent of any calendar and concepts like "day"
42/// or "month". It is related to Timestamp in that the difference between
43/// two Timestamp values is a Duration and it can be added or subtracted
44/// from a Timestamp. Range is approximately +-10,000 years.
45///
46/// Example 1: Compute Duration from two Timestamps in pseudo code.
47///
48///     Timestamp start = ...;
49///     Timestamp end = ...;
50///     Duration duration = ...;
51///
52///     duration.seconds = end.seconds - start.seconds;
53///     duration.nanos = end.nanos - start.nanos;
54///
55///     if (duration.seconds < 0 && duration.nanos > 0) {
56///       duration.seconds += 1;
57///       duration.nanos -= 1000000000;
58///     } else if (durations.seconds > 0 && duration.nanos < 0) {
59///       duration.seconds -= 1;
60///       duration.nanos += 1000000000;
61///     }
62///
63/// Example 2: Compute Timestamp from Timestamp + Duration in pseudo code.
64///
65///     Timestamp start = ...;
66///     Duration duration = ...;
67///     Timestamp end = ...;
68///
69///     end.seconds = start.seconds + duration.seconds;
70///     end.nanos = start.nanos + duration.nanos;
71///
72///     if (end.nanos < 0) {
73///       end.seconds -= 1;
74///       end.nanos += 1000000000;
75///     } else if (end.nanos >= 1000000000) {
76///       end.seconds += 1;
