title: Parse date with 7 digits in microseconds part
body: <p>I'm trying to parse Atom feed and it contains date like this one</p>
  
  <pre><code>2019-02-28T06:11:12.0775241Z
  </code></pre>
  
  <p>The problem with it is microseconds 0775241, which is 7 digits, but php can handle only 6 digits. This date is probably generated with Go lang. </p>
  
  <p>If it had 6 digits, Y-m-d\TH:i:s.u\Z would work fine. </p>
  
  <p>UPD: it is for DateTime::createFromFormat, can't use new DateTime etc. </p>
  
  <p>Looking for solution, may be you had same problem as me. </p>
