Components range from days down to milliseconds. Zero components are skipped, at most maxParts components are emitted, and a duration without any nonzero component, Duration.ZERO included, formats as "0s". Negative durations get a leading minus sign and infinite durations format as "Infinity".
Parameters
maxParts
the maximum number of components to include, at least 1.
Throws
when maxParts is less than 1.
