As previously mentioned, this is what I try to do, but just adding a 'Date taken' field to be entered when uploading a photograph (even if only approximate in the case of older pictures) would seem to be the easiest answer?

NB - If photographs are renamed, resized, rotated, cropped or otherwise modified in any way (e.g. contrast or colour balance) the date / time metadata will probably be lost so it would appear very difficult to automatically extract the required information in many cases?
