Hi Stephen,
The dateOptionalTimeParser() approach almost does what I want.
However, I'd like to enforce/validate the presence of hour/minute/second.
I've come up with the following, does it look correct to you?
----------
public class ExtendedISODateTimeFormat {
private static final DateTimeFormatter FORMAT;
static {
FORMAT = new DateTimeFormatterBuilder()
.append(ISODateTimeFormat.date())
.append(literalTElement())
.append(ISODateTimeFormat.hourMinuteSecond())
.appendOptional(fractionElement())
.append(offsetElement())
.toFormatter()
.withZone(DateTimeZone.UTC);
}
public static DateTimeFormatter dateTimeOptionalMillis() {
return FORMAT;
}
private static DateTimeFormatter literalTElement() {
return new
DateTimeFormatterBuilder().appendLiteral('T').toFormatter();
}
private static DateTimeParser fractionElement() {
return new
DateTimeFormatterBuilder().appendLiteral('.').appendFractionOfSecond(3,
9).toParser();
}
private static DateTimeFormatter offsetElement() {
return new DateTimeFormatterBuilder().appendTimeZoneOffset("Z",
true, 2, 4).toFormatter();
}
}
----------
Thanks,
-tt
