This exists for correspondence chess -- under your chess settings you can unclick the auto-claim wins on time option.
new option when time per move expires

I'm not sure it makes much sense in Live chess -- the clock is so much more integral a part of the game at those time controls that I'd be surprised if you could.
At a minimum, it should register the game as a win/loss and adjust ratings and then allow you to play on unrated, otherwise the ratings would be adversely affected.
When the time per move expires on my opponent. Give me the option to extend the time or claim the victory. If the game is really good, I would rather extend it than claim a few points. Just an idea.
Thanks in advance.
