Re: using -if with DateTimeOriginal to test for Null Data
Oh. But that didn't handle the case that the date/time is missing. Try this instead:

-if "not $dateTimeOriginal or $dateTimeOriginal !~ /^[12]/"

(you were close with "NOT $dateTimeOriginal", but the logical operators are all lower case in Perl.)
