      Description

      Druid time expressions return numeric values in form of ms (instead of formatted timestamp). Because of this expressions/function which expects its argument as string type ended up returning different values for time expressions input.

      e.g. 

      SELECT SUBSTRING(to_date(datetime0),4) FROM tableau_orc.calcs;
      | 4-07-25  |
      
      SELECT SUBSTRING(to_date(datetime0),4) FROM druid_tableau.calcs;
      | 0022400000  |
      
      SELECT CONCAT(to_date(datetime0),' 00:00:00') FROM tableau_orc.calcs;
      | 2004-07-17 00:00:00  |
      
      SELECT CONCAT(to_date(datetime0),' 00:00:00') FROM druid_tableau.calcs;
      | 1090454400000 00:00:00  |
       

      Druid needs explicit cast to make this work
