title: Why doesn't DateTime.ParseExact parse UTC format with the trailing Z?
body: <p>Another ParseExact problem. I'm trying to parse a UTC formatted string to a datetime with the format of:</p>
  
  <p><code>"YYYY-MM-DDThh:mm:ss.ssZ"</code></p>
  
  <p>which is in UTC format, with the trailing Z. I can't parse exact it for some reason. I have tried the "u", "s", "o" custom format strings, as well as as several DateTimeStyles and well as handwritten. The culture is invariant. </p>
  
  <p>For some reason it doesn't like the Z, which indicates it's a UTC string. When I remove it, parses. I would happily, with some satisfaction, get rid of the trailing Z as I know they are UTC datetime strings, but I can't. Any ideas?</p>
