- * This is a workalike of PHP's date() function, but with better

- *
- * Supported format characters are dDjlNwzWFmMntLoYyaAgGhHiscrU. See the
- * PHP manual for definitions. There are a number of extensions, which
- * start with "x":
- *
- * xn Do not translate digits of the next numeric format character
- * xN Toggle raw digit (xn) flag, stays set until explicitly unset
- * xr Use roman numerals for the next numeric format character
- * xh Use hebrew numerals for the next numeric format character
- * xx Literal x
- * xg Genitive month name
- *
- * xij j (day number) in Iranian calendar
- * xiF F (month name) in Iranian calendar
- * xin n (month number) in Iranian calendar
- * xiy y (two digit year) in Iranian calendar
- * xiY Y (full year) in Iranian calendar
- *
- * xjj j (day number) in Hebrew calendar
- * xjF F (month name) in Hebrew calendar
- * xjt t (days in month) in Hebrew calendar
- * xjx xg (genitive month name) in Hebrew calendar
- * xjn n (month number) in Hebrew calendar
- * xjY Y (full year) in Hebrew calendar
- *
- * xmj j (day number) in Hijri calendar
- * xmF F (month name) in Hijri calendar
- * xmn n (month number) in Hijri calendar
- * xmY Y (full year) in Hijri calendar
- *
- * xkY Y (full year) in Thai solar calendar. Months and days are
- * identical to the Gregorian calendar
- * xoY Y (full year) in Minguo calendar or Juche year.
- * Months and days are identical to the
- * Gregorian calendar
- * xtY Y (full year) in Japanese nengo. Months and days are
- * identical to the Gregorian calendar
- *
- * Characters enclosed in double quotes will be considered literal (with
- * the quotes themselves removed). Unmatched quotes will be considered
- * literal quotes. Example:
- *
- * "The month is" F => The month is January
- * i's" => 20'11"
- *
- * Backslash escaping is also supported.
- *
- * Input timestamp is assumed to be pre-normalized to the desired local
- * time zone, if any.
- *
- * @param $format String
- * @param $ts String: 14-character timestamp
- * YYYYMMDDHHMMSS
