Yes you can do that, but you would not use the UIImagePickerController to create the time,
but would use a NSDate and NSDateFormatter to create an NSString that could be saved to
a file.

You would properbly create these other classes and NSString in one of the UIImagePickerController's delegate methiods, possably the

UIImagePickerController : didFinishPickingMediaWithInfo :

method would be a good choice.

Hope this gives you some ideas and guidance.
