Convert Unix time to a timestamp.

Interpret a seconds-since-epoch value as UTC.

SQL snippet.sql
SELECT datetime(0, 'unixepoch');

Expected output EXAMPLE

1970-01-01 00:00:00

Details

Requires SQLite 3.40 or later. Run with sqlite3 demo.db in a scratch directory. Result rows below use | between columns, without headers; client display formatting may differ. Unix epoch values are seconds, not milliseconds. The verifier uses a fresh SQLite file for each example.

Test inputs, results and environment

The exact published code ran in a dedicated Linux test container with prepared inputs. Snippet process uid 65534 with a read-only root filesystem and temporary working files. Networking disabled. Fixtures and output records are isolated from the application database. Testing covers this example and its stated checks, not every input, operating system, or runtime version. The Linux container shares its host's kernel; this is not a native Windows test.
