/* Timezone Clock */ /** * Implement a timezone-adjusted clock * . Looks for elements with class "js-tzclock" * . Supports any timezone, not just the user's or UTC * . Supports multiple clocks per page * . Supports optional daylight saving time * * Configuration is adapted from tzdata format * . Optional comments begin with # (pound/octothorpe) * . Spaces in strings must use _ (underscore) * .  Underscore is replaced with a space when running * . + (plus) is optional for positive time offsets * . Basic zone definition must come before any rules * . Rules, if there are any, must be in chronological order * . NAME is location name displayed in clock (any string) * . UTCOFF is offset from UTC ([+|-]hh[:mm]) * . ZONE is the timezone name (any string) * . IN is the month name for a rule (3-letter in English) * . ON is the date (numerical date, lastDay, or Day>=date) * .  If used, Day is 3-letter in English * . AT is the standard time at which the rule takes effect (24-hour) * . SAVE is the amount of time added to standard time (hh[:mm]) * . LETTERS is the zone name when the rule is in effect (any string) * * Example clock configurations: * * * # NAME          UTCOFF  ZONE * New_York       -5:00   EST * # IN   ON      AT      SAVE    LETTERS * Mar    Sun>=8  2:00    1       EDT # 2nd Sunday in March * Nov    Sun>=1  2:00    0       EST # 1st Sunday in November *  * *  * # NAME          UTCOFF  ZONE * London         0:00    GMT * # IN   ON      AT      SAVE    LETTERS * Mar    lastSun 1:00    1       BST # last Sunday in March * Oct    lastSun 1:00    0       GMT # last Sunday in October *  * *  * # NAME          UTCOFF  ZONE * Tokyo          9:00    JST # no daylight time in Japan *  * *  * # NAME          UTCOFF  ZONE * Adelaide       +9:30   CST * # IN   ON      AT      SAVE    LETTERS * Apr    Sun>=1  2:00    0       CST # 1st Sunday in April * Oct    Sun>=1  2:00    1       CDT # 1st Sunday in October *  * * ... may not be essential *  for all clock configurations, but it is recommended *  to stop MediaWiki from interfering with them */ (function ($) {	'use strict';
