Michael Osipov created LANG-1003:
------------------------------------

             Summary: DurationFormatUtils are not able to handle negative durations/periods
                 Key: LANG-1003
                 URL: https://issues.apache.org/jira/browse/LANG-1003
             Project: Commons Lang
          Issue Type: Bug
          Components: lang.text.*
    Affects Versions: 3.3.2
            Reporter: Michael Osipov
            Priority: Critical


It spits out complete garbage.

{code}
System.out.println(DurationFormatUtils.formatDurationHMS(-3454));
System.out.println(DurationFormatUtils.formatPeriodISO(4000, 3000));
{code}

{noformat}
0:00:-3.-454
P-1Y11M30DT23H59M59.000S
{noformat}

I should throw an {{IllegalArgumentException}} if duration is < 0 or period diff is < 0.
