Description

DurationFormatUtils only allow to exclude leading or trailing zeroes, but not empty parts alltogether, e.g. when a position is 0 (0 days or hours).

This would improve readability and look better in most cases where the duration can vary between seconds or days and I don't want to special case, e.g. having it print
2s instead of 0d 0h 00m 02s.
