Hi.
My first thought is to make a Clock object that has a time attribute and
start() and stop() methods

Then have one instance of Clock for each player (and perhaps an independent
one for the board?)

If you have Player objects, perhaps they could have a clock instance. In
that way
you could do something like:

# suppose the players are maintained by the board in a list
# and you have a turn variable for accessing the player whose turn it is to
play
while board.state != STALEMATE and board.state != CHECKMATE:
    player = player[turn]
    player.clock.start()
    player.move()
    player.clock.stop()
    turn.next()   # adjust turn index to let other player move next round


you could even have player.clock.start() and player.clock.stop() at the
start
and end of the inside of player.move() so your code looks more like this

while board.state != STALEMATE and board.state != CHECKMATE:
    player[turn].move()
    turn.next()


Just an idea,
Sean
