It looks like that text like "2 seconds ago" has been changed to "just now". This makes sense with time that has ended, like the time of posting questions/answers/comments.
When trying to accept an answer one also gets this time text in a message, like this:
You can accept an answer in 30 seconds
However, with the "just now" update the wording in this case has become a little weird:
It says it's possible to accept an answer 'just now' but in fact it's not possible at the moment you get the message.
Although this may sound like nitpicking, I'd like to propose changing it to something more meaningful.
