[jira] [Commented] (LANG-1462) After version Commons-lang3.4 DateFormatUtils has a bug

["Chen (Jira)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/LANG-1462?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16923034#comment-16923034 ] 

Chen commented on LANG-1462:
----------------------------

The TimeZone parameter of the format method is used to create an instance of FastDateFormat with an empty default value, so I don't think this is a BUG.

Just need to modify the method description.
