title: What file name placeholders are available for Serilog?
body: <p>I use Serilog on a .NET Core application with RollingFile. I wonder, if there are different filename placeholders? I only know {Date}.</p>
  
  <p>For example, I have code like</p>
  
  <pre><code>        Log.Logger = new LoggerConfiguration()
              .MinimumLevel.Information()
              .WriteTo.RollingFile("Logs/{Date}.log")
              .CreateLogger();
  </code></pre>
  
  <p>Are there any other options for the filename like {Date}? I'd like to have log files by hour.</p>
