11  * Default {@link JdtFormatter} uses <b>ISO 8601</b> specification, enhanced by some
12  * custom patterns. For more info see:

15  * <p>
16  * Patterns list:
17  *
18  * <ul>
19  * <li>YYYY + year</li>
20  * <li>MM + month</li>
21  * <li>DD + day of month</li>
22  * <li>D - day of week</li>
23  * <li>MML - month name (addon)</li>
24  * <li>MMS - month abbreviation (addon)</li>
25  * <li>DL - day of week name (addon)</li>
26  * <li>DS - day of week abbreviation (addon)</li>
27  * <li>hh + hour</li>
28  * <li>mm + minute</li>
29  * <li>ss + seconds (no milliseconds)</li>
30  * <li>mss + milliseconds (addon)</li>
31  * <li>ss.mss + seconds.milliseconds (addon)</li>
32  * <li>DDD - day of year</li>
33  * <li>WW - week of year</li>
34  * <li>WWW - week of year with 'W' prefix</li>
35  * <li>W - week of month (addon)</li>
36  * </ul>

38  * <p>
39  * Patterns notted with + sign are used both for conversion and parsing,
40  * but all patterns are used for conversion.
41  * <p>
42  * todo Add more patterns for timezone etc
43  * todo Add new formater for SimpleDateFormatter-alike patterns
