        # "^File Modification"
        # "^Create Date"
        # "^Date/Time Orig"
        # others??

        # 2) # if no good date tag - qu: which to test? need to look at examples read-only first
        # Take Date Options:
        # a) take Earliest  Date of all in exifdata ?
        # b) takeDateFromFile()  # this should test for eg 2004-01-04..08-23:21 etc, heavily fuzzy
        # c) take date from input arg ?
