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

767 * YYYYMMDDHHMMSS
