This object is simply a unique numeric identifier that names one specific timed (limited-duration) entitlement record, distinguishing it from other pay-per-view or promotional grants in the timed entitlement table. An admin or billing system references this ID when looking up or canceling a particular pay-per-view purchase, since it's the key that ties together the channel, the customer, and the expiration time for that one transaction. A pay-per-view boxing match purchase might be recorded as timedEntitlementId 4821, linking that specific transaction to its channel and stopTime.
