TOPIC: All comments show as posted at the same time

I have Joomlacomment running nicely on a site but there is one weird thing. All comments appear to have been posted at 11 minutes past the hour.

For example, the module displays the last 3 comments:

15.11.2008-10:11 LARUA
is it free completely free though?
13.11.2008-12:11 CHARLES
This sounds good but there have been plenty ...
13.11.2008-12:11 LAW LAW
What with all their lycra costumes it is about time there...

It's always like this, any ideas?

Ah what? On your live site it is to see that there are comment posted at 47, 51 minutes and so on.

On the module on the right named "Your Comments" it shows 3 comments - (above the big blue advert).
They all show posts at :11 past the hour?

aha. Where did you download the plugin from?

I downloaded it from :
joomlacode.org/gf/project/joomagecomment/frs/
Linked from Joomla.org

Will it be too much to uninstall and install it again?
