I wonder why it's a cosine-based formula, rather than linear.

I wonder why it's a cosine-based formula, rather than linear.
- anothermachine 14y agoFor smoothness, I presume, to avoid a sudden change in the rate of time passage at the start and end of the day.
- raldi 14y agoI don't follow -- wouldn't a linear approach yield a maximally even rate of adjustment?
- BHSPitMonkey 14y agoNo, there would be continuity breaks at the beginning and end of the window where the smear occurs if purely linear. I think the goal here is a kind of "ease-in-out" transition.
- shalmanese 14y agoCosines are smooth at every level of differentiation.
- kentonr 14y agoMaybe they chose it because they wanted to "ease" in the change to prevent the machines from distrusting the time server?
