Freeze time to avoid a race condition
where a second is ticking in the middle
of a unit test.

Whether we estimate or not, the actual stored count should always be
normalized within the range of 0-cap. Estimation should always skip if
the current count is at the cap; in that case, the count can only be
changed when we get the value from the API through setCount() (used
when the value is known, rather than estimated.)
