    Default forum post timings

    How accurate are forum post timings - and is there something strange going on?

    I made a post here

    http://forums.opensuse.org/english/g...ml#post2613297

    on the successful posting my post was the second listed. What is currently the second post was not there.

    The post stamp for me as you can see is 2:11 (I assume UTC time - 6:11pm my time)

    Then at 6:20pm my time I get an email notification that a reply has been made to this thread.



    but when I return to the thread my post is number 3 and the email I have received the notification for is post #2.

    How is this even possible?
    I should not be getting notifications for posts made before me - or posts made after me should not be listed before the earlier post??????

    The time stamp for the current #2 post is 2:08UTC
    so if that is correct then I should not have received a notification, right?

    My guess is that Uwe posted using the NNTP interface (Maybe Uwe can confirm this).

    NNTP posts are converted into the Forums every 5 or 10 minutes or so (I do not know exactly, but this is enough to explain the phenomenon imho). So an NNTP post can be send (and timed) before yours, but be processed by the converter later then yours. It will however get it's original time stamp and put in the sequence as such.

    Accordingly the e-mails are send when the post is cvonverted and not when it is posted through NNTP. And, as you were subscribed at the time the e-mails are send, you get one.

    And yes, such a double advice can be the result. Same btw if two members are preparing a post and send it of in the same minute.

    You may have hit a Vbulletin bug here. I know Uwe posted through NNTP, but that shouldn't make a difference in these timings. I suggest you report this to the admins.

    EDIT: forget it. It's no more than the NNTP and webinterface not being in sync during the time window for NNTP.

    NNTP posts come through "on the sixes" generally, so times won't always
    be correct.

    The same is true on the NNTP side - the times seen there are not going to
    reflect the original post's time, because the NNTP server stamps the time
    when the post is made (rather than letting the client determine the time).

    Uwe posted via nntp, and these posts are threaded. He posted at 02:08:26 MST, but it was sent to the
    web side on 02:16 (the sixes, as Jim says).

    Your post was made "02:11" (and sent to nntp at 02:16:01), thus later than the one from Uwe, so
    yours is number 3 in the time order.

    You see Uwe post later than yours, but it was in fact sent earlier. That's what you can not see by
    looking at the web side timestamps, you have to get those from the nntp side.


    The timings are very accurate, but there are more things than you thought ;-)

    so then is it a bug that I got a reply notification for a post made before mine or is it just an anomaly that will happen from time to time because of the two forum interfaces being used?

    It's something that I would expect perhaps to see from time to time, yes.

    I wouldn't worry about it. The notification is on a thread you wanted to
    be notified on, so it's proper that you should receive a notification.

    No, bug, no anomaly. It is something that happens. I'll try again.

    Code:
    02:05    jmdl posts on web (so #1).
    02:06:01 jmdl post is sent to nntp side.
    02:08:26 Uwe answer arrives to the nntp server. You can not see it, though.
    Other nntp users can see it, though.
    It is #2
    02:11    You post. It is #3.
    02:16    Uwe post is copied to the forum server, timestamped 02:08, and now you can see it.
    02:16:01 Your post is copied not nntp side.
    02:16:xx A notification for Uwe post is created about this time.
    02:20    You get an email notification (for Uwe post).
    Yes, it is strange when it happens, seen from the web side, but everything is correct.
