> 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.
