Thank you very much for your answer.

My need is not a date formatting issue depending on the language of the instance as the article says.

My need is to manage diferent time zones (GMT +- xxxxxx) in the diferents sql server instances runnin in the same physical server.

For example, the function getdate() executed at the same time in an instance with timezone 'Madrid' and in an instance with timezone 'Chile' I would like it returns '08/08/2013 08:00:00' for the 'Madrid' instance and '08/08/2013 02:00:00' for the 'Chile' instance.

Is it posible by configuration and/or installation settings?

Thanks again in advance.

Jesús
