On what platforms are you ( both recording and playback ) ? matroska 
container is timestamp based, if you start recording at timestamp 
0:00.00.000 h ( in ns ) at every morning , you can easily jump to what 
was happening at 16:30 h by seeking the CUE table for this timestamp. 
Our DirectShow filter should allow to jump to a specifictime even after 
a small modification, with a  specific player ( we know the MPC guy and 
the TCMP guys ( http://corecoded.com ) . Let me know if we can  help.
