Muxing to file from specified time - is it possible?

[StellarWind]

The situation is:
I receive audio and video streams encapsulated in TS (or other container) over network using VLC. I need to watch and record them into file, but record from specified time (for example I see something interesting and want to record that). Also I want to stop recording at a specified time and continue watching.
Is it possible in VLC? How do I send some kind of message to the muxer to start and stop recording?
