I don't think so. I suppose you could let some time expire.
Time odds

Actually you can give time to your opponent (or they can give to you). This could be used for time odds. There is a "give 15 seconds" link in the game chat.

Is there a way to assign time odds to a game where each player starts with different amounts of time on their clock?
