org.springframework.format.datetime.standard.DurationFormatterUtils

public abstract class DurationFormatterUtils
extends Object

Support Duration parsing and printing in several styles, as listed in DurationFormat.Style.

Some styles may not enforce any unit to be present, defaulting to DurationFormat.Unit#MILLIS in that case. Methods in this class offer overloads that take a DurationFormat.Unit to be used as a fall-back instead of the ultimate MILLIS default.
