I think this looks OK. I wonder however whether it might not hurt to add a “round trip” sub-test which would write out the image containing the CreationTime and then read it back in and verify that the time was actually written to the image. I think this is optional so if you want to go ahead with the patch as-is that is fine.

By ensuring that every update to Standard/ Document/ ImageCreationTime is reflected on the ArrayList of the last decoded text chunk with Creation Time, we also ensure that Creation Time would be written to output by the PNGImageWriter. Hence no additional changes will be required in PNGImageWriter file.
