Journal Receiver automating aged deletion

Working on automating deleting detached journal receivers *n* months after
they are detached.
I can get a list of the receivers into a pf using DSPOBJD but it doesn't
indicate detach date/time.
I can get the detached time with DSPJRNRCVA but it's a noisy spooled file,
not a pf.
Then there's the Retrieve Journal Receiver Information
(QjoRtvJrnReceiverInformation) API.
It looks to me like I've missed something simple here.
TIA for suggestions.
