After publishing a workbook which utilizes the Tableau Data Update Time feature, the incorrect time-zone is displayed.
For workbooks published to Tableau Server or Tableau Cloud, the Data Update Time will use the system time from the operating system on the computer hosting Tableau Server/Tableau Cloud.
For the Tableau published workbook using the Data Update Time that is displaying the incorrect timezone, use one of the below workaround options:
Specify the Tableau Cloud system time-zone after the <Data Update Time> function.
Replace the Data Update Time function with a CURRENT_TIMESTAMP field from the dataset and calculation to specify the desired time time-zone.
Note: <Data Update Time> is not available to be used in a calculated field. In the above article, instead of a date field, use NOW() to approximate <Data Update Time> on a live connection. On an extracted connection, NOW() will not work as desired. However, for some data sources it may be possible to convert the connection to a custom SQL connection and add a CURRENT_TIMESTAMP field that will return the time the extract was created.
System time for each Tableau Cloud environment:
10ay: US Pacific
10az: US Pacific
US-East-1: UTC
US-East-a : UTC
US-East-b : EDT
US-West-2a : UTC
US-West-2b : UTC
Dub01: UTC
