/** * 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: May 2023 * 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.
