if (my @matches = grep defined, $ftime =~
/(\d+)(?:-(\d+)(?:-(\d+)(?:\s+(\d+)(?::(\d+)(?::(\d+))?)?)?)?)?/) {
... $matches[0]..$matches[6] are now set as many as are defined...
}
Your first example was broken in that you weren't testing the overall
match, and if that had failed, you would have gotten the *previous* match.
Bad News.
