> The Javadoc for DateUtils.round() does not define the behavior fully.
> For example, what is the result of:
> round(MINUTE) on 28 Mar 2002 13:10:12.499
> round(MINUTE) on 28 Mar 2002 13:10:12.500
> round(MINUTE) on 28 Mar 2002 13:10:12.501
> round(HOUR) on 28 Mar 2002 13:29:59.999
> round(HOUR) on 28 Mar 2002 13:30:00
> round(HOUR) on 28 Mar 2002 13:30:01
> How are MONTHs/YEARs rounded? Is the time taken into account?
> Does the rounding for February depend on whether there is a leap year?
> What does it mean to round to SEMI_MONTH?
