Change Time Settings
There are a couple of time-related configurations you might make when working with Tableau Cloud.
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.
Timestamps displayed across your Tableau Cloud site is in Coordinated Universal Time (UTC) of the pod that your site is deployed to. To ensure the time on your computer matches the time used by your site, you can synchronize your computer's system clock with UTC using one of the following suggestions:
If your computer is deployed on Amazon Web Services (AWS), you can synchronize your computer's system clock using Network Time Protocol (NTP) sources as described in the Keeping Time With Amazon Time Sync Service(Link opens in a new window) blog post on the AWS website.
If your computer is deployed outside of AWS, you can synchronize your computer's system clock using one of the National Institute of Standards and Technology (NIST) time servers as described in Set your computer clock via the Internet using tools built into the operating system(Link opens in a new window) page on the NIST website.
