Bruno P. Kinoshita commented on IMAGING-319:
--------------------------------------------
Hmm, odd. I have a photo I took with my Samsung phone in New Zealand, where
Offset Time is +12:00 in exiftool. When I run the example code, it works fine
with the old and the new code. Might be some other field in my test image, or
negative/positive sign.
