Description

Get unexpected output for rounding by minutes or seconds.

public void testRound()
{
Calendar testCalendar = Calendar.getInstance(TimeZone.getTimeZone("GMT"));
testCalendar.set(2007, 6, 2, 8, 9, 50);
Date date = testCalendar.getTime();
System.out.println("Before round() " + date);
System.out.println("After round() " + DateUtils.round(date, Calendar.MINUTE));
}

--2.1 produces
Before round() Mon Jul 02 03:09:50 CDT 2007
After round() Mon Jul 02 03:10:00 CDT 2007 – this is what I would expect

--2.2 and 2.3 produces
Before round() Mon Jul 02 03:09:50 CDT 2007
After round() Mon Jul 02 03:01:00 CDT 2007 – this appears to be wrong
