hazah's sandbox: Date Sort

This module is intended to resolve a problem for views that use need to sort on multiple date fields in the same way the Date Views module allows you to filter on multiple date fields. It implements the exact same interface as filtering to select the fields (both date module fields and core dates on nodes, users, etc... are made available) and uses the same sorting logic as provided by views with the exception of combining them into a coalesced value.

This module makes it possible to create far more elaborate lists based on dates in many different combinations of date fields.
