I've searched high and low - when 0-round trip is configured, what is the duration of time that session resumption can be accomplished? Is this parameter configurable? Thanks in advance.

The server sends a lifetime with the resumption key material. The RFC says the maximum time is 7 days, but that's configurable on the server; I expect people would configure it similar to lifetimes for session ticket keying. Clients may have lifetime limits as well; or they may not want to store the key material on disk, so you'd be limited to the lifetime of client execution.
