I see how that works BBW, but my point is that no one would set an overall time limit which would actually be so short that a person who plays a move per day would actually get timed out.

Your example of a 50 hour overall limit would never happen. If for example a game of Reversi, with about 33 moves per person, would never have an overall time limit of less than 33 days, so you could never time someone out by moving one minute after them everyday.

Even a 33 day limit would be better than the 9 month games some have.
