Description Matt Heitz

When we convert a string containing February 29th to a date, it "rolls forward" to March 1st.

Here's a testcase.  The first assignment works fine.  The second turns Feb 29 into March 1.  The third does the same thing, even though 2011 isn't a leap year.

handler TestRUI type RUIHandler { onConstructionFunction = start }
	function start()
		d date;

		d = "02/28/2012";
		SysLib.writeStdout( d );

		d = "02/29/2012";
		SysLib.writeStdout( d );

		d = "02/29/2011";
		SysLib.writeStdout( d );
	end
end

Fixed with changes to the runtime (egl.processFunction and helper functions).  We now add a property to the Date object to keep track of when we've seen Feb 29.  Once we're done parsing, if the flag is set we make sure the year is a leap year and then reset the date to Feb 29 because it may have rolled forward.

The testcase now correctly assigns 02/29/2012 in the second assignment.  The third assignment now correctly throws an exception (because 2011 isn't a leap year, so it doesn't have a Feb 29).
