Hi! Just curious, what's the type of use case you have in mind for this?
There's no built-in feature for time-limited sessions, although you could probably implement this at least on the server side and have a script that runs in the background and automatically terminates the process on the port after 1 hour.
I've also answered a question about adding a countdown in the UI a while ago that could potentially be relevant: misc issues: hiding buttons, implementing countdown - #2 by ines
