[Mono-dev] DateTime.ParseExact bug ?

[huseyin cakir]

It seems that the error comes if you enter the Z/T to the end of parse
string.
-------------------------------------------------------------------------
CODE 1:
System.Globalization.CultureInfo provider = new
System.Globalization.CultureInfo("tr-TR");

DateTime dt = DateTime.ParseExact( "1984-09-17T09:00:00",
"yyyy-MM-dd'T'HH:mm:ss.FFF",provider);
-------------------------------------------------------------------------
OUTPPUT 2:
9/17/1984 9:00:00 AM
-------------------------------------------------------------------------
CODE 2:
System.Globalization.CultureInfo provider = new
System.Globalization.CultureInfo("tr-TR");
 DateTime dt = DateTime.ParseExact( "1984-09-17T09:00:00Z",
"yyyy-MM-dd'T'HH:mm:ss.FFF'Z'",provider);
-------------------------------------------------------------------------
OUTPPUT 2:
