In time-limit games, I matter-of-factly announce during the ground rules that injuries will stop the clock, as will any stalling. During some games, I have also announced, when one team, for example, seems to be stalling so that the inning will finish after the deadline, that we are going to play the next inning. Over the years, I've seen teams get away with disgraceful delaying tactics, but I've also seen umps lay down the law. Ultimately, though, baseball and time limits are inherently incompatible.

JRutledge has it right in his post. The better the players, the easier it is to umpire.
