ISO-8601 (yyyy-MM-dd'T'HH:mm:ss.SSSZ)

6)

+ *
+ * <p>
+ * For date/time formatting, you can use date/time conversion
characters with argument 1:
+ * </p>
+ * <ul>
+ * <li><js>"%1$tc"</js> - Complete date and time (e.g., "Tue Mar
22 13:11:31 PDT 2011")
+ * <li><js>"%1$tb"</js> - Month abbreviation (e.g., "Mar")
+ * <li><js>"%1$td"</js> - Day of month (01-31)

+ * <li><js>"%1$tH"</js> - Hour (00-23)
+ * <li><js>"%1$tM"</js> - Minute (00-59)
