SQL 2012 :: Convert Datetime Into Date In SSIS

I have define two variable of Datetime type @Sdate and @Edate.

1. @Sdate = DATEADD ("DD", -5, GETDATE())
2. @Edate = GETDATE()
3. Using Forloopcontainer for pulling the data into batches
( @sdate = dateadd ( "HH" , 1, @sdate))

Now since i am using getdate() to define @Sdate. my variable gets data as ( 2014/12/08 11:43:00AM)

Converting GETDATE( 2014/12/08 11:43:00AM) to only date 2014/12/08 00:00:00AM.

I tired using DT_WSTR which works fine (converting datetime int String).

Problem occurs when i am going through For Loop container . Since i have used assignment of @Sdate is says its not allowed.
