This article explores the challenge of grouping timestamp data across timezones in Google BigQuery. For Unix timestamp data stored in GMT/UTC, when users need to filter and group by local timezones (e.g., EST), BigQuery's standard SQL offers built-in timezone conversion functions. The paper details the usage of DATE, TIME, and DATETIME functions, with practical examples demonstrating how to convert timestamps to target timezones before grouping. Additionally, it discusses alternative approaches, such as application-layer timezone conversion, when direct functions are unavailable.
