# Data Source Time Zone

## Data Source Time Zone

The Web server time zone field contains the time zone of your web server. Webtrends uses this time zone to translate date and time fields in your web activity data to local time. A day’s worth of data is determined by the time zone selected, setting the boundaries for daily unique visitors.

**JavaScript Example:**

```
window.webtrendsAsyncInit = function () {
        var dcs = new Webtrends.dcs();
        dcs.init( {
                dcsid: "dcs9x99xxxx9xxx9xx9xxxx9x_9x9x",
                timezone: -8
        });
        dcs.track();
}
```
