public static final class Duration.Builder
extends GeneratedMessageLite.Builder<Duration,Duration.Builder>
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".Protobuf type

getSeconds
public long getSeconds()Signed seconds of the span of time. Must be from -315,576,000,000 to +315,576,000,000 inclusive. Note: these bounds are computed from: 60 sec/min * 60 min/hr * 24 hr/day * 365.25 days/year * 10000 years
int64 seconds = 1;
- Specified by:
getSeconds
in interfaceDurationOrBuilder
- Returns:
- The seconds.
-
setSeconds
Signed seconds of the span of time. Must be from -315,576,000,000 to +315,576,000,000 inclusive. Note: these bounds are computed from: 60 sec/min * 60 min/hr * 24 hr/day * 365.25 days/year * 10000 years
int64 seconds = 1;
- Parameters:
value
- The seconds to set.- Returns:
- This builder for chaining.
-
clearSeconds
Signed seconds of the span of time. Must be from -315,576,000,000 to +315,576,000,000 inclusive. Note: these bounds are computed from: 60 sec/min * 60 min/hr * 24 hr/day * 365.25 days/year * 10000 years
int64 seconds = 1;
- Returns:
- This builder for chaining.
-
getNanos
public int getNanos()Signed fractions of a second at nanosecond resolution of the span of time. Durations less than one second are represented with a 0 `seconds` field and a positive or negative `nanos` field. For durations of one second or more, a non-zero value for the `nanos` field must be of the same sign as the `seconds` field. Must be from -999,999,999 to +999,999,999 inclusive.
int32 nanos = 2;
- Specified by:
getNanos
in interfaceDurationOrBuilder
- Returns:
- The nanos.
-
setNanos
Signed fractions of a second at nanosecond resolution of the span of time. Durations less than one second are represented with a 0 `seconds` field and a positive or negative `nanos` field. For durations of one second or more, a non-zero value for the `nanos` field must be of the same sign as the `seconds` field. Must be from -999,999,999 to +999,999,999 inclusive.
int32 nanos = 2;
- Parameters:
value
- The nanos to set.- Returns:
- This builder for chaining.
-
clearNanos
Signed fractions of a second at nanosecond resolution of the span of time. Durations less than one second are represented with a 0 `seconds` field and a positive or negative `nanos` field. For durations of one second or more, a non-zero value for the `nanos` field must be of the same sign as the `seconds` field. Must be from -999,999,999 to +999,999,999 inclusive.
