JV games around here are an untimed 7 innings, unless part of a double header (possibly with a trailing varsity game) in which case they're 5 innings and usually an 1:15 time limit.

Now, the first game for my DD's JV game this season (not a double header), the game started 10 minutes early, and after the top of the fourth, with the home team up 7-2, the PU calls the game (at about 1:15). Later I found out he told the coaches there would be an 1:15 time limit at the plate meeting, which was a surprise to the home coach (and later, the AD).
