The default time zone for extract-based data sources in a site is Coordinated Universal Time (UTC).
To set the site time zone for extracts:
- Sign in to Tableau as an administrator.
- On the site you want to configure, click
- In the
Site Time Zone for Extractssection, select a time zone and then click
In calculated fields, functions such as NOW() or TODAY() look at the time zone. For more information about Extracts, see Extract Your Data in the Tableau Desktop help.
The timezone setting, in addition to being used for extract-based data sources, also affects internal extracts. For example, when Tableau connects to file-based data sources like text files, an extract is automatically created internally. Similarly, this happens where Tableau uses an internal extract to integrate data from different sources.
