The real time map is showing a negative amount of seconds ago that a page view happened - this in turn causes no animation of the circle when a new page view happens. Keywords: realtime map
Can you please post screenshot of that bug?
That "bug" is quite easy to explain: The server time and your local computer time don't match. The "[x] time ago" strings are computed on your computer based on the timestamp that the server recorded for the visit. The time on your computer is probably running a few seconds behind and that's why the visits seem to come from the future.
I'd vote for wontfix.
Although I agree that your theory makes sense, it does not explain how I get this error on two seperate computers both on my server and on the piwik demo. I will however verify the time on both my server and local computers and report back.
But even if this is an issue, there is surley a way to prevent this from happening.
Both, the Piwik Demo and your own server are probably synced with the ntp service - so their clocks match. The only solution is to ensure your local time is synced with a time server.
Okay, so I will give it to you that updating my time did in fact fix the negative seconds. However, it did not fix the missing animation.
I believe this will be fixed in git master after this pull request is merged https://github.com/piwik/piwik/pull/235
