A close up of the clock may help with the character of the plant.
I only took one close up of the clem itself, I thought it would be fairly easy to identify when I got home. How wrong can you be !!!
Looking in your database the nearest I can find is Cultivar Name: Virginiana but it doesn't tell me much about it in the entry except that it flowers earlier than Sweet Autumn, but I don't know when that is!
edited because I can't get my fingers to hit the right keys this morning!
