Subject [jira] [Created] (LANG-1267) FastDateFormat does not support timezone X/XX/XXX in SimpleDateFormat
Date Sat, 17 Sep 2016 05:56:20 GMT
Hyukjin Kwon created LANG-1267:
----------------------------------

             Summary: FastDateFormat does not support timezone X/XX/XXX in SimpleDateFormat
                 Key: LANG-1267
                 URL: https://issues.apache.org/jira/browse/LANG-1267
             Project: Commons Lang
          Issue Type: Bug
          Components: lang.time.*
    Affects Versions: 3.3.2
            Reporter: Hyukjin Kwon


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

For example, 

{code}
new FastDateFormat("yyyy-MM-dd'T'HH:mm:ss.SSSXXX")
{code}

throws an exception as below:

{code}
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)
{code}


{{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.
