A. that's super funky use of sprintf
B. you really need to take a look at POSIX::strftime and it's red headed brother, POSIX::strptime. Both give you the same feels as sprintf if that's what you're needing
I mark my journey as a programmer by moments of sheer awe when I discover something awesome. That combo is one of those times. The other was when I first learned to create a mailto: link in my college computer lab in the 90s. These 2 events were roughtly 19 years apart and the ones that stick out most in my mind. Good luck.

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).
