For my little script I just looked for .pngs in remotecache that weren't in any of my storage directories. All the PNGs in my remotecache just duplicated ones that were created alongside my recordings. That ought to satisfy most needs if recordings are watched and (eventually) deleted like I think most people do. No need for any *time. My script is meant for my FE/BE case but using the Services API a bit more I think it could be used on a FE or a FE/BE.
