title: asp.net datetime randomly duplicate time offset. is a bug?
body: <p>i have a website developed in asp.net 4 and sql server 2008 R2.
  The problem is very complicated.
  I have a field in db with datatime offset UTC (ex. 2015-09-30 18:24:53.1498113 +02:00).
  Randomly (i think when application pool restart) this value return corrupt after query in .net like this:
  30/09/2015 18:21:00 +02:00 +02:00
  Time offset repeated 2 times!</p>
  
  <p>So, when i parse the date in c# obviously i receive an error "String was not recognized as a valid DateTime".</p>
  
  <p>If i recycle pool applcation page work fine</p>
  
  <p>Why? It's a bug? Have you ever seen similar problem?</p>
  
  <p>Thanks a lot</p>
