Steps to Reproduce:
* Select the ISO 8601 format in your preferences (this is the default if your locale is French for example)
* Visit https://phabricator.wikimedia.org/T13267 (jsut an example, I just pick here a bug submitted years ago)
You'll see that
* **years are not displayed**, it's impossible to see accurate dates for bugs or comments submitted years ago !
* the ISO 8601 format is in fact not used at all, instead the en-US format is used (but with months or abbrevs translated in the user's language, and incorrecly ordered)
Current workaround:
* We MUST select the English (US?) locale to see years.
* We don't know which timezone is used for time.
Actual Results:
* "fév 22 AM, 10:57" (if French is the selected UI language)
* which is complete non-sense (in French days of the month should be *before* the month name, abbreviated here)
* the "AM/PM" makes no sense at all in French: note that the default is already using the 24-hours format.
Expected Results:
* "22 fév 2014, 10:57" (for the normal French format), or
* "2014-02-22 10:57" (for the ISO 8601, if using the local time from the locale), or
* "2014-02-22T10:57Z" (for the standard ISO 8601 format in the UTC timezone)
