Pass correct Time object to CA DataCollector

This change makes sure that the underlying query works properly if Date
parameters are given. The `created_after` parameter will be casted to
Time to contain the beginning of the day time. The `created_before`
parameter will be casted to Time to contain the end of the day time.
