What steps will reproduce the problem?

base::TimeDelta minute = base::TimeDelta::FromMinutes(1);
RecentEventsCounter counter(base::TimeDelta::FromHours(1), 60);

counter.Log(65 * minute);
counter.Log(66 * minute);
int a = counter.GetTotal(66 * minute);
int b = counter.GetTotal(66.5 * minute);

What is the expected result?
a and b should both be 2.

What happens instead?
a and b are both zero.

We are using a circular array to store the values for each minute.
The problem is reading the entire array. We need to read from
minute 6, up to minute 59, then from minute 0 up to minute 5. The code says start at minute 6 and keep going and until you get to minute 6. Unfortunately, we are already at minute 6 at the beginning so we never loop around the array.
