title: Prototype mismatch: sub main::strftime
body: <p>In my perl program am using <code>use POSIX qw( strftime );</code> library to perform unixtimestamp to date conversion as follows,</p>
  
  <pre><code>my $dt = strftime("%m/%d/%y", localtime($fields[0]));
  </code></pre>
  
  <p>Conversion is happening as expected but am getting the following error.</p>
  
  <pre><code> Prototype mismatch: sub main::strftime ($\@;$) vs none at 
   /usr/lib/perl5/5.8.5/Exporter.pm line 67.
   at /usr/lib64/perl5/5.8.5/x86_64-linux-thread-multi/POSIX.pm line 19
  </code></pre>
  
  <p>Has anyone guide me what is the reason and how to get rid of it?</p>
