 This function should look for where cell phones and cameras store timezone
 offset data.

 Storing the time as a timestamp is a mistake as the time in exif data is
 minus the timezone and in whatever time the device was set to, it would
 have been better to store as a formatted time as converting to timezone
 means that everything is off.

 EXIF supports storing timezone offset in several places, if there we
 should use it, otherwise assume site timezone.
