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.
