Checking for expired ClaimsPrincipal cookie

In the "About cookie expiration" section, the following explains how to set an expiration time. Could something be added on how to check if a ClaimsPrincipal cookie is expired? I can't find this information anywhere in the docs.

> An absolute expiration time can be set with ExpiresUtc. To create a persistent cookie, IsPersistent must also be set. Otherwise, the cookie is created with a session-based lifetime and could expire either before or after the authentication ticket that it holds.
