Hi pavelcarcass,

the answer is fortunately easy but unfortunately bad news. The $timezone variable does not relate to the client. It only relates to the setup of the MetaMod, to what the timezone drop down is set to.

A web client does not normally send information about which time zone it is in, to the web server, as part of its web request.

The time zone may be able to be deduced if you use the GeoLiteCIty database, and want to work with the $geoip->longitude variable. It's not perfect, but I imagine that the longitude and the time zone generally are related. But it won't be perfect, and I don't know if every IP address will necessarily have a longitude associated with it.

From this page:

http://stackoverflow.com/questions/5584 … like-geona

I see this, for rough calculations:

"However, some very rough approximation can be calculated: 1 hour difference corresponds to 15 degrees longitude (360 / 24)."

Does that help?

Cheers,
Stephen

You can have a look at the comparisons with the different databases at www.maxmind.com. The commercial database is a little more accurate, but not that much (last time I looked). And it varies enormously between countries.

If the issue is about determining location, then it's really not Joomla that's the problem. The question is really about which underlying technologies you have available for determining location. You could look for alternative GeoIP databases, or alternatively look at JavaScript methods for requesting location data, which will often be highly accurate if the user is on a GPS-equipped mobile and gives you permission.

Hope that helps,
Stephen
