Brian Brazil 4c8173acac Use timestamp of a sample in deriv() to avoid FP issues (#2958) 
With the squaring of the timestamp, we run into the
limitations of the 53bit mantissa for a 64bit float.

By subtracting away a timestamp of one of the samples (which is how the
intercept is used) we avoid this issue in practice as it's unlikely
that it is used over a very long time range.

Fixes #2674
