createdTime property
CreatedTime is when the machine came into being: the provider's own creation timestamp for a Visor machine, passed through in whatever form it states it, and for a BYO machine the RFC 3339 moment it first dialed in.
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
String? createdTime;
