title: Bug in DateTime.ToString("T") and DateTime.ToString("G")?
body: <p><a href="https://docs.microsoft.com/en-us/dotnet/standard/base-types/custom-date-and-time-format-strings?redirectedfrom=MSDN" rel="nofollow noreferrer">Microsoft specifies</a> <code>:</code> as <code>The time separator</code>, but it seems there are at least two time separators: one between hours and minutes and another one between minutes and seconds.</p>

  <p>Is there a way to get the specific time separators? I need the one between hours and minutes and the other one between minutes and seconds.</p>
  
  <p>I would also not mind building my DateTime string in other ways, e.g. using the <a href="https://docs.microsoft.com/en-us/dotnet/standard/base-types/standard-date-and-time-format-strings?redirectedfrom=MSDN" rel="nofollow noreferrer">standard format string</a> <code>T</code> or <code>G</code>, but they both don't work</p>
  
  <pre><code>mydate.ToString("T");
  // Output: 20-29-46
  // Expected output: 20-29:46 (as shown by Windows clock)
  
  mydate.ToString("G");
  // Output: 09/03-2014 20-29-46
  // Expected output: 09/03-2014 20-29:46
  </code></pre>
