Sort timestamp strings by their parsed instants.
JavaScript: Compare epoch values explicitly when date strings may contain different offsets.
const values = ["2026-01-01T10:00:00Z", "2026-01-01T09:30:00Z"];
values.sort((a, b) => Date.parse(a) - Date.parse(b));
console.log(values.join("\n"));Expected output EXAMPLE
2026-01-01T09:30:00Z 2026-01-01T10:00:00Z
Details
Save as snippet.js and run node snippet.js. Uses built-in Node.js and JavaScript APIs. Compare epoch values explicitly when date strings may contain different offsets.

Test inputs, results and environment
The exact published code ran in a dedicated Linux test container with prepared inputs. Unprivileged snippet process, external networking disabled, read-only root filesystem, and a fresh temporary working directory. 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.
