 <div class="block"><p>FastDatePrinter is a fast and thread-safe version of
  <a href="https://docs.oracle.com/javase/8/docs/api/java/text/SimpleDateFormat.html?is-external=true" title="class or interface in java.text"><code>SimpleDateFormat</code></a>.</p>

  <p>To obtain a FastDatePrinter, use <a href="../../../../../../../org/apache/logging/log4j/core/util/datetime/FastDateFormat.html#getInstance-java.lang.String-java.util.TimeZone-java.util.Locale-"><code>FastDateFormat.getInstance(String, TimeZone, Locale)</code></a>
  or another variation of the factory methods of <a href="../../../../../../../org/apache/logging/log4j/core/util/datetime/FastDateFormat.html" title="class in org.apache.logging.log4j.core.util.datetime"><code>FastDateFormat</code></a>.</p>

  <p>Since FastDatePrinter is thread safe, you can use a static member instance:</p>
  <code>
      private static final DatePrinter DATE_PRINTER = FastDateFormat.getInstance("yyyy-MM-dd");
  </code>

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

  <p>Only formatting is supported by this class, but all patterns are compatible with
  SimpleDateFormat (except time zones and some year patterns - see below).</p>

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

  <p>In addition, the pattern <code>'ZZ'</code> has been made to represent
  ISO 8601 extended format time zones (eg. <code>+08:00</code> or <code>-11:00</code>).
  This introduces a minor incompatibility with Java 1.4, but at a gain of
  useful functionality.</p>

  <p>Starting with JDK7, ISO 8601 support was added using the pattern <code>'X'</code>.
  To maintain compatibility, <code>'ZZ'</code> will continue to be supported, but using
  one of the <code>'X'</code> formats is recommended.

  <p>Javadoc cites for the year pattern: <i>For formatting, if the number of
  pattern letters is 2, the year is truncated to 2 digits; otherwise it is
  interpreted as a number.</i> Starting with Java 1.7 a pattern of 'Y' or
  'YYY' will be formatted as '2003', while it was '03' in former Java
  versions. FastDatePrinter implements the behavior of Java 7.</p>
