+// 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 = ...; |
