time goes like c# string -- immutable.
drop it, it's collected, as a garbage, by the system.
updating, what's updated is only another instance based on the original bytes.
new one, what you got is just a new one, the old one is still unchanged, floating as an orphan in the memory space.
the value never changes -- immutable, until collected or, the process exits.
