If the type is a time/date, then the type character - * {@code t} is followed by an additional character that indicates how the - * date is to be formatted. The two characters {@code <$} immediately - * following the % sign indicate that the previous value should be used again - * instead of moving on to the next value argument. A number {@code n} - * and a dollar sign immediately following the % sign make n the next argument - * to be used. - * - * <p>The available choices are the following: - * - * <table BORDER="1" WIDTH="100%" CELLPADDING="3" CELLSPACING="0" SUMMARY=""> -
