When using regular expressions it is usually a good idea to put them in a condition.
if ( my ( $raw_dt, $refs ) = /^(.*) UTC.*refs = (\d+)$/ ) {
my $dt = $Strp->parse_datetime($raw_dt);
...
}
else {
# possible error condition
}
The greater danger of your code, apart from using uninitialized $1 and $2, is using an initialized $1 and $2 from a previous match. The capture buffer variables $1 etc are not reset to undef when a match fails so you may produce erroneous output without any outward sign.

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).
