Brent Worden updated LANG-815: ------------------------------ Summary: DurationFormatUtils.formatPeriod() miss-calculation (was: DurationFormatUtils.formatPeriod() miss-calcuration) > DurationFormatUtils.formatPeriod() miss-calculation > --------------------------------------------------- > > Key: LANG-815 > URL: https://issues.apache.org/jira/browse/LANG-815 > Project: Commons Lang > Issue Type: Bug > Components: lang.time.* > Affects Versions: 3.1 > Environment: JDK 1.7 > Reporter: Naoya Sugioka > Attachments: duration-format.diff > > Original Estimate: 1h > Remaining Estimate: 1h > > Hello, > I just encountered an issue with DurationFormatUtils.formatPeriod() > and here I suggest the patch. > The problem is found when calcurating a duration between June 30 to August 8. > Duration must be 1 month and 9 days (June 30 + 1 month = July 30, > July 30 + 9 Days = August 8) > but current logic tells this duration is 1 month and 8 days. > then I found out the logic to adjust days value if it was negative by > initial estimate. it uses start date > (June in above case) but must use prev month of end date (July in > above case). then days value was > wrong since getActualMaximum() will return a wrong number. > thank you, > -Naoya -- This message is automatically generated by JIRA.
