Thanks Steve, it is so easy to transpose one form.
So i did try all three of these and they work
"Wed, 02 Oct 2015 08:00:00 EST"
"Wed, 02 Oct 2015 13:00:00 GMT"
"Wed, 02 Oct 2015 15:00:00 +0200"
Note if the date you enter is in the past , like this
"Wed, 02 Oct 2002 15:00:00 +0200"
Then you get the not very helpful "Invalid Date" message.
