I took a trip to a different time zone and shot a bunch of pictures, without changing the time on my digital camera. The problem is that the EXIF data shows the times the pictures were shot using my home time zone, rather than the time zone of the place I actually shot the pictures. So a picture I shot at breakfast looks like it was taken at midnight, based on the EXIF data.

Many applications let you set an absolute date / time in the EXIF data. But this great application lets you set a relative time -- so if the time zone difference is three hours, you can select all your pictures, and change the time field in the EXIF to three hours earlier than what's shown.

It's a great feature for people who can't be bothered to change the time on their digital camera when they're travelling. Thanks for a great application.
