lastPurgeAt property
LastPurgeAt is when the edge cache was last cleared, as Unix seconds, so a console can say how fresh what readers see actually is. Absent means never.
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? lastPurgeAt;
