The tutorial text describing the Mog Clock says that if you let the timer into the red, you're immediately forced into battle and that if you lose that battle you don't get the retry option. What actually happens in that case?
In most games I would expect you to get kicked back to the title screen, but with autosaving (and being able to save manually almost anywhere) that doesn't seem like much of a punishment here, but it must do something bad or there would be no reason to implement this. I'm afraid to try, personally, without knowing what will happen.
