When you add a connection to a database, you set the value for the Database Time Zone on the Connection Settings page: For example, to convert from UTC to EST, you could create a column with the table calculation add_hours(-5, $). If you need to adjust timestamps in an i_looker or a System Activity Explore, Looker recommends using table calculations to create time-adjusted columns. Changing the system time zone is not trivial and is not recommended. Customer-hosted instances may be in a different system time zone. For Looker-hosted instances, the system time zone is always set to UTC. The system time zone is not configurable through the Looker application. Looker's internal database, which stores the information available in the i_looker and System Activity Explores, stores time-based data in the system time zone. The system time zone is the time zone for which the server running Looker is configured. Several settings within Looker specify how to convert time-based data: This also means that queries run using SQL Runner do not convert time-based data. The underlying data is not affected rather, the query results are converted using Looker's time zone settings. Looker converts time-based data when it generates SQL during a query for a Look, an Explore, or a dashboard. For example, a user in New York viewing data created in California doesn't have to manually subtract three hours to filter or interpret their queries. Users can see query results and create filters with time-based data that is converted to their local time zones. Looker can make time-based data easier to understand by converting it to different time zones.
