UTC, Unix Time & ISO 8601 Tools

Essential time formats for developers and APIs

This page provides essential developer tools built on the IANA timezone database — the authoritative, globally maintained registry of timezone identifiers used by every major operating system, programming language runtime, and API. Whether you are building a scheduling API, parsing timestamps from a third-party service, or debugging a timezone-related bug in production, these utilities give you live, accurate reference values. Convert any Unix timestamp to a human-readable date, inspect the current UTC offset and ISO 8601 string for your environment, and copy your local IANA identifier — the exact string your API or database driver needs — with one click. Code examples for JavaScript and Python are included so you can drop correct timezone-aware logic directly into your codebase. All data is computed client-side using the browser's native Intl API, meaning no external API call is required and results are always in sync with the IANA database version shipped with your runtime.

Code Examples

JavaScript

// Get current Unix timestamp
const timestamp = Math.floor(Date.now() / 1000);

// Convert Unix timestamp to Date
const date = new Date(timestamp * 1000);

// Get ISO 8601 string
const iso = new Date().toISOString();

Python

import time
from datetime import datetime

# Get current Unix timestamp
timestamp = int(time.time())

# Convert Unix timestamp to datetime
dt = datetime.fromtimestamp(timestamp)

# Get ISO 8601 string
iso = datetime.now().isoformat()
