Description

It sees FastDateFormat does not support timezone X/XX/XXX in SimpleDateFormat.

For example,

FastDateFormat.getInstance("yyyy-MM-dd'T'HH:mm:ss.SSSXXX")

throws an exception as below:

Illegal pattern component: XXX
java.lang.IllegalArgumentException: Illegal pattern component: XXX
	at org.apache.commons.lang3.time.FastDatePrinter.parsePattern(FastDatePrinter.java:282)
	at org.apache.commons.lang3.time.FastDatePrinter.init(FastDatePrinter.java:149)
	at org.apache.commons.lang3.time.FastDatePrinter.<init>(FastDatePrinter.java:142)

X/XX/XXX are different with Z or ZZ as described in https://docs.oracle.com/javase/7/docs/api/java/text/SimpleDateFormat.html#iso8601timezone

It supports to read all +0800, +08 and +08:00 whereas it seems there is no way to include those all.

I looked though the documentation multiple times but I could not find the explicit mention about this.
