+Summary: Convert.ChangeType fails to convert TimeSpan objects
+
+Description of Problem:
+the Convert.ChangeType method throws an exception when trying to convert to
+ TimeSpan object even if the source object is also a TimeSpan
+
+Steps to reproduce the problem:
+run this code:
+using System;
+using System.Globalization;
+
+static void TestTimeSpan(){
+ System.TimeSpan tspan = Convert.ToDateTime("2000-12-01") -
+Convert.ToDateTime("2000-01-01");
+ Convert.ChangeType(tspan, typeof(System.TimeSpan),
+CultureInfo.InvariantCulture);
+}
+
+Actual Results:
+Unhandled Exception: System.InvalidCastException: Value is not a
+convertible object: System.TimeSpan to System.TimeSpan
+in <0x008aa> System.Convert:ToType (object,System.Type,System.IFormatProvider)
+in <0x00013> System.Convert:ChangeType
+(object,System.Type,System.IFormatProvider)
+
+
+Expected Results:
+a successful conversion to a new TimeSpan object
+
+How often does this happen?
+consistently
+
+Additional Information:
+the above code works fine on windows. This only seems to be an issue with
+TimeSpan - although I didn't test other object types exhaustively.
