CFSET time to today at 9:00PM

I need to update my SQL database at the end of each day for certain records.

The time needs to be 9:00 PM each day (dont worry about time differences)

So for today  I need to insert '2013-06-21 21:00:00' into the db.

So I wantd to set the time before I inserted it.

How do I do that?

<CFSET mytime = ?>

How do I get 9:00 PM each day?
