Maybe not quite what you had in mind... but my engine is aware of the opponent's
clock and whether its a human or computer.  It uses this imformation to adjust
the value of a draw at the start of each move.  (Yes, I am aware there will
still be info in the hash table based on stale draw scores but the draw value
changes so slowly that I choose to ignore this).  If an opponent is in time
trouble (different definition for human opponent and computer opponent) the
value of a draw becomes very negative so that hopefully it wins on time.
