Class Duration

  • All Implemented Interfaces:
    DurationOrBuilder, com.google.protobuf.Message, com.google.protobuf.MessageLite, com.google.protobuf.MessageLiteOrBuilder, com.google.protobuf.MessageOrBuilder, java.io.Serializable
    public final class Duration
extends com.google.protobuf.GeneratedMessageV3
implements DurationOrBuilder
     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".
