How Can a Time-Based Asset Transition Its Fungibility?

A time-based asset transitions its fungibility by having its associated smart contract logic change based on a timestamp. For instance, a token representing a subscription could be fungible until the subscription expires, at which point the contract prevents further transfers, or the metadata is updated to reflect its new, non-fungible status as an expired collectible.
