Meta Stack Exchange is where users like you discuss bugs, features, and support issues that affect the software powering all 131 Stack Exchange communities.

I saw a question that was posted 9 mins ago. I checked the user's profile and it says seen 12 mins ago. How is that possible? Does it mean it took 3mins for the post to appear? Or its a bug?

How often is the last seen updated? Could we have a user online//offline indicator?

The answer is caching.

The "last seen" date/time is cached and not updated every time the user does something. So it's perfectly possible for an answer to be posted later than the latest "last seen".
