EventLogQuery time format expected?

Question

I\'m trying to use the EventLogQuery class to query the eventlog. I followed the example shown on http://msdn.microsoft.com/en-us/library/bb671200%28v=vs.90%29.aspx#Y0.

Here's a C# example for initializing an EventLogQuery object that will only load event entries from the last day.

var yesterday = DateTime.UtcNow.AddDays(-1);

var yesterdayDtFormatStr = yesterday.ToString(
   "yyyy-MM-ddTHH:mm:ss.fffffff00K", 
   CultureInfo.InvariantCulture
);

var query = string.Format(
   "*[System/TimeCreated/@SystemTime >='{0}']", 
   yesterdayDtFormatStr
);

var elq = new EventLogQuery("Application", PathType.LogName, query);
