It depends on how the program implements the time control, of course. If
the program just adjusts its depth setings etc. according to the time
spent on previous moves, then this shouldn't be a problem: it should do
so according to the "time_left" reports it gets via GTP from kgsgtp.
Just logging the GTP stream should make everything reproducible.
