/** * Warning! Global gadget file! * * This gadget adds a clock in the personal toolbar that shows the current time * in UTC (or a different timezone of your choosing), and also provides a link * to purge the current page. * * Revision: July 2020 * Source: https://www.mediawiki.org/wiki/MediaWiki:Gadget-UTCLiveClock.js * * Installation: * * 1. Copy the JS page at https://www.mediawiki.org/wiki/MediaWiki:Gadget-UTCLiveClock.js * to the page [[MediaWiki:Gadget-UTCLiveClock.js]] on your wiki. * * 2. Copy the CSS page at https://www.mediawiki.org/wiki/MediaWiki:Gadget-UTCLiveClock.css * to the page [[MediaWiki:Gadget-UTCLiveClock.css]] on your wiki. * * 3. Copy the CSS page at https://www.mediawiki.org/wiki/MediaWiki:Gadget-UTCLiveClock-pagestyles.css * to the page [[MediaWiki:Gadget-UTCLiveClock-pagestyles.css]] on your wiki. * * 4. Add a description of the gadget to the page [[MediaWiki:Gadget-UTCLiveClock]] * on your wiki. You can use https://www.mediawiki.org/wiki/MediaWiki:Gadget-UTCLiveClock * as a template. * * 5. Add the following code to your wiki's [[MediaWiki:Gadgets-definition]]: * * * UTCLiveClock[ResourceLoader|type=general|dependencies=mediawiki.util,mediawiki.api|peers=UTCLiveClock-pagestyles]|UTCLiveClock.js|UTCLiveClock.css * * UTCLiveClock-pagestyles[hidden|skins=vector,monobook]|UTCLiveClock-pagestyles.css * * * To set the timezone used to one other than UTC, set window.LiveClockTimeZone to * the desired timezone. For example, adding the following to your common.js * window.LiveClockTimeZone = 'America/Los_Angeles'; * would result in the local time in Los Angeles being shown. See * [[:w:List of tz database time zones]] for valid options (use the TZ database name). * * If you find a seconds counter distracting, set: * window.LiveClockHideSeconds = true; * */ /*global mw, $ */ mw.loader.using( ['mediawiki.util', 'mediawiki.api'] ).then( function () { function padWithZeroes( num ) { // Pad a number with zeroes.
