We used the cosine smear only for leap 34.  The smears for leaps 35
and 36 were linear
(https://cloudplatform.googleblog.com/2015/05/Got-a-second-A-leap-second-that-is-Be-ready-for-June-30th.html).

The linear smear deals with the leap by having only two frequency
changes (instead of an infinite number), so it's admirably simple.
