title: How to a create a daily build folder using buildbot?
body: <p>I want to save a copy of the nightly build, I figured putting each build into its own daily folder would be idea. However I cannot use the time from buildbot master.cfg because that it set when it is configured:</p>
  
  <pre><code>copy_files = [".\\release\\MyProgram.exe",
                ".\\install\\ChangeLog.js",
                ".\\translations.txt"]
  server_dest_path_by_date = server_dest_path + "\\{0}".format(time.strftime("%Y-%m-%d"))
  my_return.addStep(steps.MakeDirectory(dir=server_dest_path_by_date))
  for file in copy_files:
      my_return.addStep(ShellCommand(command=["copy", file, server_dest_path_by_date, "/y"]))
  </code></pre>
  
  <p>How would I get the current run date for use in the destination?</p>
