By making a move, you automatically "press your clock." It the perfect API might be to have a <press> command so that it remains your turn to move until you send that. Then you can send the move, the draw claim, and then press the clock. Since the clock is 'automatic' this is problematic since there are so many servers around. Some implement the command "draw move" which means I claim a draw after I play this move, but that isn't done everywhere, and would break in those cases.
