4 * Date Formatter class - locale-dependent formatting/parsing of dates using pattern strings and/or canned patterns.
5 *
6 * This class represents the ICU date formatting functionality. It allows users to
7 * display dates in a localized format or to parse strings
8 * into PHP date values using pattern strings and/or canned patterns.
9 *
10 * Example:
11 * <code>
12 * $datefmt = new DateFormatter("de-DE", LONG, SHORT, date_default_timezone_get());
13 * echo $formatter->format(time());
14 * </code>
15 *
16 * <code>
17 *  $datefmt = new DateFormatter("de-DE", LONG, SHORT, date_default_timezone_get() , GREGORIAN , "yyyy-MM-dd HH:mm:ss z");
18 *  echo $formatter->format(time());
19 * </code>
20 *
