> Key: LANG-982
> URL: https://issues.apache.org/jira/browse/LANG-982
> Project: Commons Lang
> Issue Type: Bug
> Components: lang.time.*
> Reporter: Sebb
> Fix For: 3.3.1
>
>
> DurationFormatUtils.formatDuration(61999, "s.SSSS") generates the wrong
> number of places for the millisecond field. It should produce 61.0999 but it
> generates 61.999.
> This is an unlikely format, but there is no indication that the millisecond
> field is a maximum of 3 digits when it happens to follow a seconds field.
> This issue occurs because of the way the code attempts to ensure that 3
> places are shown in a format if milliseconds follows seconds.
> The code currently adds 1000 and then drops the first digit.
> The simplest way to allow an arbitrary number of digits is to use at least 3
> for the count field.
> Alternatively, if exactly 3 digits are required it would be simpler to just
> use a count of 3.
