If the program doesn't honor the EXIF info and uses the file's timestamp
as "the time the photo was taken", then there's not much we can do and
the time will often be wrong for whatever reason (e.g. you copied the
files).

So what we should do is check the EXIF info: if the photo's date is
missing, we should take the file's timestamp and put it as the
photo's date.  Then we can go on and change the file's time stamp all
we want.
