Problems with System.DateTime.Parse

DateTime objects, from my memory, are not specific to any region conceptually though the ToString and Parse methods are probably in US format. I would make a separate method to print the date in Australian format, and when you parse the date, parse it from a US format string instead of an Australian format. change CADSTime = System.DateTime.Parse(FoundDay + "/" + FoundMonth + "/" + FoundYear + " " + FoundTime) to CADSTime = System.DateTime.Parse(FoundMonth + "/" + FoundDay + "/" + FoundYear + " " + FoundTime) Your program is probably not even working properly with your current code. Check the value of CADSTime in the debugger, and I'm guessing it'll say it's January 7th, not the July 1st you intended.
