public final class Duration
extends GeneratedMessage
implements DurationOrBuilder

Protobuf type google.protobuf.Duration

 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 = end.nanos - start.nanos;
     if (duration.seconds < 0 && duration.nanos > 0) {
       duration.seconds += 1;
       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;
     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;
     }

  - getDefaultInstanceForType
```
public Duration getDefaultInstanceForType()
```
    Description copied from interface: MessageLiteOrBuilder
    
    Get an instance of the type with no fields set. Because no fields are set, all getters for singular fields will return default values and repeated fields will appear empty. This may or may not be a singleton. This differs from the getDefaultInstance() method of generated message classes in that this method is an abstract method of the MessageLite interface whereas getDefaultInstance() is a static method of a specific class. They return the same thing.
