For time fields, allow specifying a range of times, then 19/20 times,
specify "from" and "to" times in that range when querying those fields,
rather than just looking at the standard view all the time.
More generally, report QPS not at 0 queries, which is boring, but every
100 queries *and* after the last query if the last query wasn't at a
multiple of 100 queries. Makes the output slightly more useful, I think.
