 /**
 30  
  * <p>FastDateFormat is a fast and thread-safe version of
 31  
  * {@link java.text.SimpleDateFormat}.</p>
 32  
  *
 33  
  * <p>To obtain an instance of FastDateFormat, use one of the static factory methods:
 34  
  * {@link #getInstance(String, TimeZone, Locale)}, {@link #getDateInstance(int, TimeZone, Locale)},
 35  
  * {@link #getTimeInstance(int, TimeZone, Locale)}, or {@link #getDateTimeInstance(int, int, TimeZone, Locale)}
 36  
  * </p>
 37  
  *
 38  
  * <p>Since FastDateFormat is thread safe, you can use a static member instance:</p>
 39  
  * <code>
 40  
  *   private static final FastDateFormat DATE_FORMATTER = FastDateFormat.getDateTimeInstance(FastDateFormat.LONG, FastDateFormat.SHORT);
 41  
  * </code>
 42  
  *
 43  
  * <p>This class can be used as a direct replacement to
 44  
  * {@code SimpleDateFormat} in most formatting and parsing situations.
 45  
  * This class is especially useful in multi-threaded server environments.
 46  
  * {@code SimpleDateFormat} is not thread-safe in any JDK version,
 47  
  * nor will it be as Sun have closed the bug/RFE.
 48  
  * </p>
 49  
  *
 50  
  * <p>All patterns are compatible with
 51  
  * SimpleDateFormat (except time zones and some year patterns - see below).</p>
 52  
  *
 53  
  * <p>Since 3.2, FastDateFormat supports parsing as well as printing.</p>
 54  
  *
 55  
  * <p>Java 1.4 introduced a new pattern letter, {@code 'Z'}, to represent
 56  
  * time zones in RFC822 format (eg. {@code +0800} or {@code -1100}).
 57  
  * This pattern letter can be used here (on all JDK versions).</p>
 58  
  *
 59  
  * <p>In addition, the pattern {@code 'ZZ'} has been made to represent
 60  
  * ISO 8601 extended format time zones (eg. {@code +08:00} or {@code -11:00}).
 61  
  * This introduces a minor incompatibility with Java 1.4, but at a gain of
 62  
  * useful functionality.</p>
 63  
  *
 64  
  * <p>Javadoc cites for the year pattern: <i>For formatting, if the number of
 65  
  * pattern letters is 2, the year is truncated to 2 digits; otherwise it is
 66  
  * interpreted as a number.</i> Starting with Java 1.7 a pattern of 'Y' or
 67  
  * 'YYY' will be formatted as '2003', while it was '03' in former Java
 68  
  * versions. FastDateFormat implements the behavior of Java 7.</p>
