digital camera radio controlled clock integrated

I'm looking for a reasonable digital camera (5 to 7 mega pixels) with a radio controlled clock built in.  In England we have clock which are controlled by radio waves and I would like this to be intergated into the camera so when a picture is taken the time and date is stamped onto the image automatically.

The purpose of this is to have a certified time and date when the picture was taken.

I can be contacted anytime.

I need to know how much the units would cost each and by the 100.

I am based in England.
