If you need the filename separately considering the domain you might use Path::Tiny (or File::Basename) to split things up before you then apply your regex. It's semantically clearer what you're trying to do as well as isolating you from platform differences in directory separators. 

my $filename = path( $path )->basename;
my( $date, $time ) = $filename =~ m{## as others have shown}x;
