605 * This is a workalike of PHP's date() function, but with better
606 * internationalisation, a reduced set of format characters, and a better
607 * escaping format.
608 *
609 * Supported format characters are dDjlNwzWFmMntLoYyaAgGhHiscrU. See the
610 * PHP manual for definitions. "o" format character is supported since
611 * PHP 5.1.0, previous versions return literal o.
612 * There are a number of extensions, which start with "x":
613 *
614 * xn Do not translate digits of the next numeric format character
615 * xN Toggle raw digit (xn) flag, stays set until explicitly unset
616 * xr Use roman numerals for the next numeric format character
617 * xh Use hebrew numerals for the next numeric format character
618 * xx Literal x
619 * xg Genitive month name
620 *
621 * xij j (day number) in Iranian calendar
622 * xiF F (month name) in Iranian calendar
623 * xin n (month number) in Iranian calendar
624 * xiY Y (full year) in Iranian calendar
625 *
626 * xjj j (day number) in Hebrew calendar
627 * xjF F (month name) in Hebrew calendar
628 * xjt t (days in month) in Hebrew calendar
629 * xjx xg (genitive month name) in Hebrew calendar
630 * xjn n (month number) in Hebrew calendar
631 * xjY Y (full year) in Hebrew calendar
632 *
633 * xmj j (day number) in Hijri calendar
634 * xmF F (month name) in Hijri calendar
635 * xmn n (month number) in Hijri calendar
636 * xmY Y (full year) in Hijri calendar
637 *
638 * xkY Y (full year) in Thai solar calendar. Months and days are
639 * identical to the Gregorian calendar
640 * xoY Y (full year) in Minguo calendar or Juche year.
641 * Months and days are identical to the
642 * Gregorian calendar
643 * xtY Y (full year) in Japanese nengo. Months and days are
644 * identical to the Gregorian calendar
645 *
646 * Characters enclosed in double quotes will be considered literal (with
647 * the quotes themselves removed). Unmatched quotes will be considered
648 * literal quotes. Example:
649 *
650 * "The month is" F => The month is January
651 * i's" => 20'11"
652 *
653 * Backslash escaping is also supported.
654 *
655 * Input timestamp is assumed to be pre-normalized to the desired local
656 * time zone, if any.
657 *
658 * @param $format String
659 * @param $ts String: 14-character timestamp
660 * YYYYMMDDHHMMSS
661 * 01234567890123
662 * @todo emulation of "o" format character for PHP pre 5.1.0
663 * @todo handling of "o" format character for Iranian, Hebrew, Hijri & Thai?
