title: EventLogQuery time format expected?
body: <p>I'm trying to use the EventLogQuery class to query the eventlog.  I followed the example shown on <a href="http://msdn.microsoft.com/en-us/library/bb671200%28v=vs.90%29.aspx#Y0">http://msdn.microsoft.com/en-us/library/bb671200%28v=vs.90%29.aspx#Y0</a>.</p>
  
  <p>I've searched Google a ton but can't find any queries with the @SystemTime not hard-coded in there.</p>
  
  <p>Does anyone know the DateTime format I need to use for this?  Everything I've tried so far has returned "Invalid Query" exceptions.</p>
