What is Unix Timestamp?

Unix timestamp (also called Epoch time) is a way to track time as a running total of seconds since January 1, 1970 at UTC. It's widely used in programming, databases, and APIs because it represents time as a simple number, making it easy to store, compare, and calculate.

For example, the Unix timestamp 1710775800 represents March 18, 2024, 2:30:00 PM UTC.

What is ISO 8601?

ISO 8601 is the international standard for representing dates and times. The format isYYYY-MM-DDTHH:mm:ssZ where the 'T' separates the date from the time, and 'Z' indicates UTC time. It's the most widely used format in modern APIs and web services.

Unix Timestamp in Programming

JavaScript

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

// Convert timestamp to date
const date = new Date(timestamp * 1000);
console.log(date.toISOString());

Python

import time
from datetime import datetime

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

# Convert timestamp to datetime
dt = datetime.fromtimestamp(timestamp)
print(dt.isoformat())

Common Questions

What input formats can I paste here?

You can paste Unix timestamps, ISO 8601 strings, many browser-readable dates, and simple relative phrases like now, today, tomorrow, or yesterday.

What is the difference between timestamp seconds and milliseconds?

Timestamp seconds are shorter Unix values like 1700000000, while milliseconds add three more digits like 1700000000000 for higher precision.

Why is ISO 8601 commonly used in APIs?

ISO 8601 is explicit, sortable, and widely supported, which makes it a reliable format for APIs, logs, databases, and cross-time-zone systems.
