User:ISO-DATE

ISO 8601 ISO 8601

Up to version 1.9 the mediawiki does not allow ISO 8601 conform installation.

I did not test Version 1.10.

problems:
 * recent changes

little hardcoded fix for english-only-use
 * messagesEn.php
 * $defaultDateFormat = 'ISO 8601';

still problematic
 * bottom of page: last change "19:43, Date" (wrong order, should be "date time" without comma)
 * signatures like "... 15:30 (CEST)" (Timezone abbreviations not allowed, should be +/- hours)

related but not needed for ISO conformance:
 * how to have UTC only in the whole wiki, i.e. 13:30Z? or if wanted "13:30 UTC"

Another problem: ISO 639 language conform installation.

 * Manual:$wgLanguageCode does not allow "mul" for multilingual wikis
