Unsupported field: Year when formatting an instant to Date ISO [duplicate]
Solution 1:
To format an Instant a time-zone is required.
String input = "20161012235959.0Z";
DateTimeFormatter f = DateTimeFormatter
.ofPattern ( "uuuuMMddHHmmss.SX" )
.withLocale( Locale.FRANCE )
.withZone( ZoneId.of("UTC"));
OffsetDateTime odt = OffsetDateTime.parse ( input , f );
Instant instant = odt.toInstant ();
System.out.println(input);
System.out.print(f.format(instant));
