There are two clocks. One is a regular clock measuring regular time τ. The other is a clock measuring time t which also advances clockwise, but does not advance uniformly--it accelerates w.r.t. τ from 12 to 6 o'clock, and decelerates from 6 to 12, such that the two clocks always tell the same time at 12 and 6. It is given that the alternating acceleration and deceleration of t w.r.t. τ is uniform--d2tdτ2=K where K is a constant. Is this enough info to determine the "dilation" dtdτ? If not, what other info is needed?
