If you only need an approximate answer, I'll invoke the "or something like that" clause and
change 196364 into '2.3d'
print sec2human(196364), "\n";
sub sec2human {
my $secs = shift;
if ($secs >= 365*24*60*60) { return sprintf '%.1fy', $secs/(365
+*24*60*60) }
elsif ($secs >= 24*60*60) { return sprintf '%.1fd', $secs/(
+ 24*60*60) }
elsif ($secs >= 60*60) { return sprintf '%.1fh', $secs/(
+ 60*60) }
elsif ($secs >= 60) { return sprintf '%.1fm', $secs/(
+ 60) }
else { return sprintf '%.1fs', $secs
+ }
}

Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big>
<blockquote> <br /> <dd>
<dl> <dt> <em> <font>
<h1> <h2> <h3> <h4>
<h5> <h6> <hr /> <i>
<li> <nbsp> <ol> <p>
<small> <strike> <strong>
<sub> <sup> <table>
<td> <th> <tr> <tt>
<u> <ul>
-
Snippets of code should be wrapped in
<code> tags not
<pre> tags. In fact, <pre>
tags should generally be avoided. If they must
be used, extreme care should be
taken to ensure that their contents do not
have long lines (<70 chars), in order to prevent
horizontal scrolling (and possible janitor
intervention).
