| // 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. |
| // |
| // Example 1: Compute Duration from two Timestamps in pseudo code. |
| // |
| // Timestamp start = ...; |
| // Timestamp end = ...; |
| // Duration duration = ...; |
| // |
| // duration.seconds = end.seconds - start.seconds; |

| // duration.nanos -= 1000000000; |
| // } else if (durations.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; |
