InspectAll fails when Event has multiple DateTime fields

[lamolley1]

Example event:

        [Event(1, Level = EventLevel.Informational)]
        public void ExampleEvent(
            DateTime datetime1,
            DateTime datetime2)
        {
            this.WriteEvent(datetime1, datetime2);
        }

The analyzer throws:

System.FormatException: 1 is not a valid value for DateTime ---> System.FormatException: String was not recognized as a valid DateTime.

When the second datetime is removed the test succeeds. Is this an eventsource limitation or a bug in the analyzer? I'm on the latest analyzer package version - 2.0.1406.1
