DateTimeText := '2013-10-02T16:10:23.456Z'; EVALUATE(NewDateTime,DateTimeText,9); MESSAGE('%1',NewDateTime);As stated in ISO 8601 http://en.wikipedia.org/wiki/ISO_8601 the Z indicates that the given datetime is UTC. When you remove the Z NAV should take it as local time. This works fine in CC. But when you do it in 2009 R2 RTC then it still takes it as UTC.
