This is a test timelapse, with ramped shutter speed from 1/800 second moving to 5 seconds, taken across a 2 hour time period with a constant 7 second interval between shots. The change in shutter speed shows the effect of shuttering, from severe at the start graduating to a smoother playback as the shutter speed tends towards (and eventually exceeds) 180 degree shutter angle. It also gives the effect of slowly speeding up playback, even though the interval remained constant throughout.
I haven't had the chance to deflicker it properly yet, hope the exposure jumps don't hurt your eyes!!!
