<pre>
Output only. The last time this queue was purged.

All tasks that were [created][google.cloud.tasks.v2beta2.Task.create_time]
before this time were purged.

A queue can be purged using
[PurgeQueue][google.cloud.tasks.v2beta2.CloudTasks.PurgeQueue], the [App
Engine Task Queue SDK, or the Cloud
Console](https://cloud.google.com/appengine/docs/standard/python/taskqueue/push/deleting-tasks-and-queues#purging_all_tasks_from_a_queue).

Purge time will be truncated to the nearest microsecond. Purge
time will be unset if the queue has never been purged.
