DateUtils Javadoc does not fully define round() behaviour
---------------------------------------------------------
Key: LANG-441
URL: https://issues.apache.org/jira/browse/LANG-441
Project: Commons Lang
Issue Type: Bug
Affects Versions: 2.4
Reporter: Sebb
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?
