How to set infinite shared access signature policy in azure?

问题

I am trying to set a shared access policy so that the user has infinite SharedAccessExpiryTime. I will track their access policies so that they can be revoked if needed.

From this thread, the answer states there is a mechanism for setting an infinite expiration time. I did some searching and was not able to find this, how can this be done?

Currently, I simulate infinite by providing some large values for expiration time:

         SharedAccessTablePolicy policy = new SharedAccessTablePolicy()
        {
            SharedAccessExpiryTime = DateTime.UtcNow.AddYears(500),

            Permissions = SharedAccessTablePermissions.Add
            | SharedAccessTablePermissions.Delete
            | SharedAccessTablePermissions.Update
            | SharedAccessTablePermissions.Query
        };

In the Spring 2012 release that went out a few weeks ago, there were updates announced to Shared Access Signatures. For blobs, the 1-hour SAS limit has been lifted. The MSDN article is here, which includes quite a bit of sample code spanning SAS for queues, tables, and blobs.
