Help with format date formula

Can anyone translate this into a usable date for the day field?

Just a few of the things I've tried:

• changing the formatting in the preview to different syntaxs like dd-MM-yyyy'T'HH:mm:ss.SSS'Z'
• PARSEDATE((SUBSTITUTE(csv['creation_time'],'T',' ')),'dd-MM-yyyy HH:mm:ss.SSS')
• PARSEDATE(SUBSTITUTE(csv['creation_time'],'T',' '),'dd-MM-yyyy HH:mm:ss.SSS z')
• PARSEDATE(csv['creation_time'],'dd-MM-yyyy'T'HH:mm:ss.SSS z')
• PARSEDATE((LEFT(csv['creation_time'],10)),'yyyy-MM-dd')
• PARSEDATE(orig-date,yyyy-MM-dd) 
  var orig-date = LEFT(csv['creation_time'],10);

Those have all passed validation,  but then when I run a evalution, I get a message like this:
