There is a little bug : most dates question , comments etc..) the year is lost. As the site is now older there are questions that are 1 2 or 3 years old and we cannot tell. May be I am missreading stuff of there is a trick such as an hovering mouse ...
If an event is
less than one year old from this calendar year (thanks quid!), the year is not written. I recognize that this is not a convention that is immediately unambiguous to new users. Perhaps we can add a feature request to make everything ISO 8601-compliant.
