durationMs property
DurationMs is wall-clock milliseconds around the completion, including a failover's retries. It is time SPENT, not time billed.
Please note: This property should have been non-nullable! Since the specification file does not include a default value (using the "default:" property), however, the generated source code must fall back to having a nullable type. Consider adding a "default:" property in the specification file to hide this note.
Implementation
int? durationMs;
