variation in results with different time step in transient structural analysis

  I am doing transient structural analysis and i need acceleration results. But when i change the time step, the response or the result also changes. Even the shape of acceleration time graph changes. How do i rectify this and how can i find out the correct time step to provide for my model. I have tried taking time step as time period/10 and time period/20 but both of these are showing different values and response graph.
  Kindly help me out
