+* Odoo default value for timezone field uses the tz set on the connected user.
+  So if a user creates a partner located in a different timezone than his own,
+  the created partner will be set in the user's timezone instead of having the
+  timezone from its own location.
+  Ideally, we should change this behaviour to get the timezone from the country
+  and city of the partner when they are defined.
+  http://www.geonames.org/export/web-services.html#timezone might be a good
+  starting point.
