createdAt property
CreatedAt is IAM's creation time as unix seconds. 0 when IAM's timestamp is absent or unparseable — never a fabricated time.
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? createdAt;
