FROM_UNIXTIME (legacy)

You are looking at legacy documentation for Firebolt’s deprecated date and timestamp type functions. New types were introduced in DB version 3.19.0 under the names PGDATE and TIMESTAMPNTZ, and made generally available in DB version 3.22.0.

If you worked with Firebolt before DB version 3.22.0, you might still be using the legacy date and timestamp types. Determine which types you are using by executing the query SELECT EXTRACT(CENTURY FROM DATE '2023-03-16');. If this query returns an error, you are still using the legacy date and timestamp types and can continue with this documentation. If this query returns a result, you are already using the redesigned date and timestamp types and can use the TO_TIMESTAMPTZ function instead.

Convert Unix time (BIGINT in epoch seconds) to DATETIME (YYYY-MM-DD HH:mm:ss).

Syntax

FROM_UNIXTIME(<unix_time>)

Example

SELECT
    FROM_UNIXTIME(1493971667);
