In our county, in Florida, the athletic director has deemed that all JV games have a two hour time limit. Not drop dead but no new inning after 2 hours unless there is a tie. Ties are to be played out. The reasoning behind this is that JV and varsity sometimes play back to back and that could end up having the Varsity game starting way late. The AD has left it up to our association as to who keeps the time. In the games that I work the base umpire will keep a watch, IN HIS POCKET, and let the plate umpire know when we are at the time limit.
