Great . Quick response
Jim's should work too (assuming you're on at least SQL 2008, but since only SQL 2005 was explicitly listed, I didn't want to assume that).
It's more a matter of style. I prefer to use things that are functional back to SQL 2005 when possible, I guess because I've got a couple of those instances I still support :) .

(Off Topic) I was wondering about the use of DATEADD, if it had something to do with performance, ergo I should add it to a bunch of places I'm supporting..
That too, in the sense that DATEADD is clearly faster than string manipulation to strip the time. Thus, it's a standard technique for me, so I stick to it when I can.
But I wouldn't expect either DATEADD or CAST to perform significantly better than the other, I'd consider them equal in terms of performance.
