720 * Supported format characters are dDjlNwzWFmMntLoYyaAgGhHiscrU. See the
721 * PHP manual for definitions. There are a number of extensions, which
722 * start with "x":
723 *
724 * xn Do not translate digits of the next numeric format character
725 * xN Toggle raw digit (xn) flag, stays set until explicitly unset
726 * xr Use roman numerals for the next numeric format character
727 * xh Use hebrew numerals for the next numeric format character
728 * xx Literal x
729 * xg Genitive month name
730 *
731 * xij j (day number) in Iranian calendar
732 * xiF F (month name) in Iranian calendar
733 * xin n (month number) in Iranian calendar
734 * xiY Y (full year) in Iranian calendar
735 *
736 * xjj j (day number) in Hebrew calendar
737 * xjF F (month name) in Hebrew calendar
738 * xjt t (days in month) in Hebrew calendar
739 * xjx xg (genitive month name) in Hebrew calendar
740 * xjn n (month number) in Hebrew calendar
741 * xjY Y (full year) in Hebrew calendar
742 *
743 * xmj j (day number) in Hijri calendar
744 * xmF F (month name) in Hijri calendar
745 * xmn n (month number) in Hijri calendar
746 * xmY Y (full year) in Hijri calendar
747 *
748 * xkY Y (full year) in Thai solar calendar. Months and days are
749 * identical to the Gregorian calendar
750 * xoY Y (full year) in Minguo calendar or Juche year.
751 * Months and days are identical to the
752 * Gregorian calendar
753 * xtY Y (full year) in Japanese nengo. Months and days are
754 * identical to the Gregorian calendar
755 *
756 * Characters enclosed in double quotes will be considered literal (with
757 * the quotes themselves removed). Unmatched quotes will be considered
758 * literal quotes. Example:
759 *
760 * "The month is" F => The month is January
761 * i's" => 20'11"
762 *
763 * Backslash escaping is also supported.
764 *
765 * Input timestamp is assumed to be pre-normalized to the desired local
766 * time zone, if any.
767 *
768 * @param $format String
769 * @param $ts String: 14-character timestamp
770 * YYYYMMDDHHMMSS
