Bug 578732

Description ANS 2022-02-14 07:59:52 EST

GUI shows wrong date after manual editing of 'day' text field in February.
Snippet to reproduce:

void testDateTimeWidget(final Composite parent) {
	final DateTime dt = new DateTime(parent, SWT.MEDIUM);
	dt.setDate(2022, 1, 10); 

        // GUI shows correct date of 10.2.2022
	// then:
	// 1. edit day text field with keyboard (or spinner)
	// 2. press 'Test' button
	// 3. GUI shows wrong date of 3.1.2022 (internal value is 31)

	final Button testDT = new Button(parent, SWT.NONE);
	testDT.setText("Test");
	testDT.addSelectionListener(new SelectionAdapter() {

		@Override
		public void widgetSelected(final SelectionEvent e) {
			dt.setDate(2022, 0, 31);
			System.out.println("day: " + dt.getDay());
		}

	});
}
