I find that the post time at up right of a page only shows month/day, I think it should be detailed with year(eg. y/m/d), especially for old posts .
If you hover over the date and time, the tooltip that appears has the post year, too.
Actually, for very old posts, it shows month 'year. The difference (a single apostrophe) with “month day” for more recent posts is quite subtle, however.
Thank you waddlesplash and PulkoMandy, I did not notice that, it is very neat
