title: How can I reformat Date Time output into ISO 8601
body: <p>Using the code below it outputs the following value:  04/10/2019 which is due to the server being set to UK date time settings.  However google is reading this date as 10 April 19.  So I need to convert it to ISO8601 formate, ie 10/04/2019</p>
  
  <pre><code>Dim FutureDate, TodaysDate
  FutureDate = FormatDateTime(Now(),1)
  TodaysDate = DateAdd("m", 0, FutureDate)
  FutureDate = DateAdd("d", +100, TodaysDate)
  
  
  "priceValidUntil": "&lt;%= FutureDate %&gt;",
  </code></pre>
