Class ISO8601Utils

  • public class ISO8601Utils
extends java.lang.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]]
