Stupid Rule or Stupid officials?

Softball, ranked 22nd, is playing Fresno State, ranked 21st. After seven full we are tied at six. There is a drop dead 3pm finish time for the game and there is less than ten minutes to 3. They go ahead and start the inning which I figured since they started it they would finish the inning. We were batting in the top half of the inning and had three runs in with runners at second and third with no outs and they call the game due to the drop dead rule. Arrrrrrrrgggggg. Very frustrating. Why did they even start the inning with so little time 'til three. I vote for stupid officials.
