I have a DateTime which I want to format to "2009-09-01T00:00:00.000Z", but the following code gives me "2009-09-01T00:00:00.000+01:00" (both lines):

new DateTime(2009, 9, 1, 0, 0, 0, 0, DateTimeKind.Utc).ToString("yyyy'-'MM'-'dd'T'HH':'mm':'ss'.'fffzzz")
new DateTime(2009, 9, 1, 0, 0, 0, 0, DateTimeKind.Utc).ToUniversalTime().ToString("yyyy'-'MM'-'dd'T'HH':'mm':'ss'.'fffzzz")

Any ideas how to make it work?
