Review Comment:
   Bycatch: this test is flaky. `[QUERY_1, QUERY_2, QUERY_3]` are executed 
consequently, with supposedly increasing `start_time`. 
   
   Since the original code `int(...)` basically rounded down the float epoch, 
the actual query results returned `[QUERY_1, QUERY_2]`---even though we 
filtered `second_query_time` by `QUERY_3`. But this still sometimes fail 
because the rounded down time can be anywhere between QUERY_1 start time and 
QUERY_3 start time, so if QUERY_1 and QUERY_2 are executed within the same 
second, we wouldn't have QUERY_2 in the filtered results. E.g. when the start 
time for the queries are `1.1, 1.5, 2`---we'd be filtered to between `[1, 1]`.
