All outputs are automatically formatted as per ISO , separating date and time with a T. Parentheses are optional when called with no arguments. See Time zone definitions for information on how to specify a time zone. The current date and time is recorded at the start of the query statement which contains this function, not when this specific function is evaluated. To ensure the function call, add parentheses; to ensure the column name, qualify it with its range variable.

The behavior you're observing is due to the way BigQuery handles timestamps. For example:. View solution in original post. In Google Cloud BigQuery, you cannot directly store timestamp columns with timezone information in the table's schema. BigQuery internally stores timestamps in UTC, regardless of the timezone specified during ingestion. It's useful for storing local dates and times without the need for explicit timezone conversion. It's a universal representation of time, independent of any particular timezone. This ensures consistency and avoids issues with daylight saving time changes across different timezones. This function effectively converts the UTC timestamp to the specified timezone. Timezone Conversion: Timezone conversion should ideally be handled at the application level or during data retrieval rather than during data ingestion. This allows for flexibility and control over how timestamps are presented to users.

By: Osheen Jain Published: December 27, When working with data in BigQuery, you may encounter timestamp fields that you want to convert to simple date values instead. However, for many analysis use cases you may only care about the date itself — the year, month, and day the event occurred on. Converting timestamp strings into date values allows you to group and aggregate your data by day, month, or year more easily. This function produces a continuous, non-ambiguous timestamp that has exactly 60 seconds per minute. Also, the Timestamp Function does not repeat values over the leap second. You can return a specific part from the supplied Timestamp expression with this command.

IMPORTANT: Before working with these functions, you need to understand the difference between the formats in which timestamps are stored and displayed, and how time zones are used for the conversion between these formats. To learn more, see How time zones work with timestamp functions. Returns the current date and time as a timestamp object. The timestamp is continuous, non-ambiguous, has exactly 60 seconds per minute and does not repeat values over the leap second. Parentheses are optional. This function handles leap seconds by smearing them across a window of 20 hours around the inserted leap second. The current date and time is recorded at the start of the query statement which contains this function, not when this specific function is evaluated. To ensure the function call, add parentheses; to ensure the column name, qualify it with its range variable. See Time zone definitions for information on how to specify a time zone.

In this post, you will learn the fundamentals of working with timestamp and datetime in BigQuery. You will see how you can create different timestamps: from a text, from the current date, and even from a number. I include as much working queries as possible, so you can also run them on your own BigQuery console.
