com.fasterxml.jackson.databind.util.ISO8601Utils

public class ISO8601Utils
extends Object

Utilities methods for manipulating dates in iso8601 format. This is much much faster and GC friendly than using SimpleDateFormat so highly suitable if you (un)serialize lots of date objects. Supported parse format: [yyyy-MM-dd|yyyyMMdd][T(hh:mm[:ss[.sss]]|hhmm[ss[.sss]])]?[Z|[+-]hh:mm]]
