title: strftime '%z', (localtime) is not working as expected in solaris machines
body: <p>I tried this code in linux machines,</p>
  
  <pre><code>my $sysdate = strftime "%Y%m%d%T", (localtime);    
  my $daylight_saving_time = strftime '%z', (localtime);
  </code></pre>
  
  <p>i get below output,</p>
  
  <pre><code>sysdate = 2013051402:12:02    
  daylight_saving_time = -0400
  </code></pre>
  
  <p>I tried same in solaries machines, i got this </p>
  
  <pre><code>sysdate = 2013051402:12:02
  daylight_saving_time = %z
  </code></pre>
  
  <p>Anyone know the change to be done to get the daylight saving in solaries machines.</p>
  
  <p>Thanks in Advance.</p>
