title: Can I put a timestamp in initializeData using TraceListener?
body: <p>It is possible to put a timestamp in the "initializeData" on the TraceListener?</p>
  
  <p>Something like this:</p>
  
  <pre><code>&lt;sharedListeners&gt;
        &lt;add name="AppSourceListener"
          type="System.Diagnostics.DelimitedListTraceListener" 
          initializeData="c:\test%date.csv" 
          traceOutputOptions="ProcessId, DateTime, Callstack"&gt;
        &lt;/add&gt;      
  &lt;/sharedListeners&gt;
  </code></pre>
  
  <p>I would like to put the DateTime.Now in every log, once the application is initiated.</p>
