Direct sound recorders like
Replay Radio and
Replay A/V have a scheduling feature. Replay Player that is a part of
Audio Video Streaming Capture Suite allows you to skip ahead in 30, 60 and 120 second increments so you can quickly skip over ads and other fluff.
Stream rippers like
StreamRipper can record and play audio stream at the same time.
As for TimeShift recording, I haven't really seen such audio recorders.
