DateUtils.isSameLocalTime does not work correct

Hi, I think I found a bug in the DateUtils class in the method isSameLocalTime.

Example:
Calendar a = Calendar.getInstance();
a.setTimeInMillis(1297364400000L);

Calendar b = Calendar.getInstance();
b.setTimeInMillis(1297321200000L);

Assert.assertFalse(DateUtils.isSameLocalTime(a, b));

This is because the method compares
cal1.get(Calendar.HOUR) == cal2.get(Calendar.HOUR)

but I think it has to be
cal1.get(Calendar.HOUR_OF_DAY) == cal2.get(Calendar.HOUR_OF_DAY)
