title: Robot Framework: Using current date in the variable is not working
body: <p>My Variables header inside my Robot file looks like:</p>
  
  <pre><code>*** Variables ***
  ${date} =  Get Current Date    result_format=%Y%m%d%H%M%S
  ${workspaceName} =  Workspace${date}
  </code></pre>
  
  <p>When I use <code>${workspaceName}</code> later in the file, it's content is "Get Current Date    result_format=%Y%m%d%H%M%S" as a string. But when <code>${workspaceName}</code> is defined inside a test case, it works correctly.</p>
  
  <p>Is it true that the Variables section can't contain functions? For example <code>Get Current Date</code>?</p>
