/**
* 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".
