What kind of ninja skills allows for a user to post a question and have the timestamp appear later than when their profile says they were sighted?

timestamp on question later than last seen

How did this user post a question without being "seen"? Shouldn't any of the main actions (posting, commenting) update the last seen field in their account?

No-repro. The user's last-seen is 10:46:05Z and the question was asked on 10:51:41Z. Both shows "1 hour ago" now. – kennytm Nov 15 '10 at 12:06
Caching? I know the profile data is cached (check your own now, I bet it doesn't say "seen 0s ago"). – ChrisF Nov 15 '10 at 12:15
@ChrisF: I assumed it would be a caching thing, but it's not client-side caching (forced reload doesn't fix it) so it could be altered at the server to update the "seen" field whenever a user performs an action that is publicly visible. Also, when I checked my profile it said "2m ago", even though I hadn't performed any public actions since posting the q. This suggests "seen" is updated on certain page views. – Andy E Nov 15 '10 at 12:19
@Kenny: doesn't that count as a repro? He was last seen 5mins 36 seconds before asking his question. – Andy E Nov 15 '10 at 12:19
I see your point. – ChrisF Nov 15 '10 at 12:20
@Andy: I must be living in Australia :p – kennytm Nov 15 '10 at 12:21
You tried again to use the [ninjas] tag, I see. – Grace Note Nov 15 '10 at 13:28
@Grace: yeah, tried :-) – Andy E Nov 15 '10 at 13:36
If you don't see them, how do you know they are ninjas? – user27414 Nov 15 '10 at 16:05

Closing as dupe of much newer post, but with a much better answer. – Shadow Wizard Dec 18 '15 at 9:20

Last seen does not mean what you think it means.

It means the last interval check that was made; someone could have activity beyond that, up to the next interval check.

What the heck is an interval check? And if "last seen" doesn't mean last seen, then why does it say "last seen" instead of "last interval check"? – Rob Kennedy Nov 15 '10 at 23:11
@rob in other words, last seen does not mean I have not seen you since I last saw you. It just means THAT was the last time I saw you. I might see you again in 2 minutes, too. – Jeff Atwood Nov 16 '10 at 2:26
@JeffAtwood - You seem to have some confusion about the meaning of the word "last". – Martin Smith Oct 6 '13 at 8:16
if we can have realtime question feed why can't user profile detail can be updated in realtime, it is clearly a bug and should have been accepted as bug OR change text to what Rob suggested – Jigar Joshi Jul 12 '14 at 18:53
@JigarJoshi this is known as status-meh. – Shadow Wizard Dec 18 '15 at 9:19
