<p>Ah, yes--that makes sense! Used the hours calculation for all four snippets:</p>
<c>
$amount = $amount * 60 * 60;
</c>
<p>and got identical results, until 79 hours was used (a result difference of 2), but I suspect the division in the <c>grep { -M >= $amount / 86400 }</c> yields a different precision.</p>
<p>Interestingly, <c>IO::All</c> didn't see the file "song自然之歌," but <c>File::Find::Rule</c> did (and should have).</p>
