If you are an anonymous user Xoops System allways shows the standard time which is defined in the generall settings of the system. But if you are logged in as a registered user the system will show the times for your defined timezone.

For example: Your Systen runs on GMT and you write an article at 09.00 am. A user from germany (who has GTM+1) is logged in and has a look at the article now will see that it has been posted at 10.00 am because it was 10.00 am in his timezone when the article has been posted.

Every user could define his timezone in his Account and on the chosen option there it depends what times he will see on the page.

At first I was also confused after registering here on this site because it is 8 hours earlier than in my timezone.
