public final class ISO8601
extends Object

The ISO8601 utility class provides helper methods to deal with date/time formatting using a specific ISO8601-compliant format (see ISO 8601).

The currently supported format is:

   ±YYYY-MM-DDThh:mm:ss.SSSTZD
 

where:

   ±YYYY = four-digit year with optional sign where values <= 0 are
           denoting years BCE and values > 0 are denoting years CE,
           e.g. -0001 denotes the year 2 BCE, 0000 denotes the year 1 BCE,
           0001 denotes the year 1 CE, and so on...
   MM    = two-digit month (01=January, etc.)
   DD    = two-digit day of month (01 through 31)
   hh    = two digits of hour (00 through 23) (am/pm NOT allowed)
   mm    = two digits of minute (00 through 59)
   ss    = two digits of second (00 through 59)
   SSS   = three digits of milliseconds (000 through 999)
   TZD   = time zone designator, Z for Zulu (i.e. UTC) or an offset from UTC
           in the form of +hh:mm or -hh:mm
