/*
* SERVER-6121: aggregation framework converts Timestamp to long long in result set
*
* This test validates the SERVER-6121 ticket. Add support for timestamps to Aggregation and
* ensure they can do everything dates can. Previously timestamps were awkwardly used as dates
* and long longs.
*/

* 1) Clear and create testing db
* 2) Run an aggregation with all date expressions on a timestamp and a date
* 3) Run an aggregation that will show timestamp and date can be compared
* 4) Run an aggregation comparing two timestamps to show inc matters
