if you want to you can just hold it open till the battery runs out it would normally be shown in seconds only way to find out is to take a photo longer than 999 seconds and see what it gives you.i have a friend who did just that (left on tripod till battery expired) didn't see the exif data though. try a search on flickr etc for your camera look for long exposures and see if the exif data is there.(some people hide it) hth mikeSo if a it is open for an hour will the time be shown in the exif as 3600 seconds or will the timer go back to 0 at after going past the 999 mark
