org.apache.commons.lang.time.FastDateFormat

FastDateFormat is a fast and thread-safe version of {@link java.text.SimpleDateFormat}.

This class can be used as a direct replacement to SimpleDateFormat in most formatting situations. This class is especially useful in multi-threaded server environments. SimpleDateFormat is not thread-safe in any JDK version, nor will it be as Sun have closed the bug/RFE.

Only formatting is supported, but all patterns are compatible with SimpleDateFormat (except time zones - see below).

Java 1.4 introduced a new pattern letter, 'Z', to represent time zones in RFC822 format (eg. +0800 or -1100). This pattern letter can be used here (on all JDK versions).

In addition, the pattern 'ZZ' has been made to represent ISO8601 full format time zones (eg. +08:00 or -11:00). This introduces a minor incompatibility with Java 1.4, but at a gain of useful functionality.
