Description

In some cases, It is frequent to test with different value for time related values on query with Experiments.

ex)

 "duration": {"from": 1454425200000, "to": 1454511600000} 

currently above changes require client to change request query body itself. it would be great to support something like this.

ex)

 "duration": {"from": "${-1 day}", "to": "${now}"} 

benefit of this support is not requiring client to change their query so more flexibility for A/B testing with experiment.
