Frequently Asked Questions

What is a Unix timestamp?
A Unix timestamp is the number of seconds that have elapsed since January 1, 1970, at 00:00:00 UTC (Coordinated Universal Time). This date is known as the Unix Epoch. It's widely used in programming and databases because it's timezone-independent and easy to calculate with.
What's the difference between Unix and JavaScript timestamps?
Unix timestamps are measured in seconds since the epoch, while JavaScript timestamps are measured in milliseconds. To convert between them, multiply Unix timestamps by 1000 to get JavaScript timestamps, or divide JavaScript timestamps by 1000 to get Unix timestamps.
What is the Year 2038 problem?
The Year 2038 problem occurs because many systems store Unix timestamps as signed 32-bit integers, which can only represent dates up to January 19, 2038, at 03:14:07 UTC. After this date, the integer will overflow. Modern systems are moving to 64-bit integers to avoid this issue.
How do I handle timezones with timestamps?
Unix timestamps are always in UTC, which makes them timezone-agnostic. When converting to a human-readable date, the timestamp is interpreted in your local timezone by default. To work with specific timezones, you'll need to apply the appropriate offset or use timezone-aware date libraries in your programming language.

Unix Timestamp Converter

A Unix timestamp (also called epoch time) is the number of seconds that have elapsed since January 1, 1970, 00:00:00 UTC — a point known as the Unix Epoch. It is the standard way computers store and communicate date/time values across programming languages, databases, APIs, and operating systems.

Our free timestamp converter lets you instantly convert between Unix timestamps and human-readable dates in any timezone. Paste a timestamp from your logs, database, or API response and immediately see the date and time it represents. Or enter a date to get its Unix timestamp in seconds or milliseconds.

How to Convert Timestamps

  1. 1

    Convert timestamp to date

    Paste a Unix timestamp (in seconds or milliseconds) into the input. The tool auto-detects the unit and displays the corresponding date and time in UTC and your local timezone.

  2. 2

    Convert date to timestamp

    Enter or select a date and time using the date picker. The tool outputs the corresponding Unix timestamp in seconds and milliseconds.

  3. 3

    Change timezone

    Use the timezone selector to see the date/time in any timezone — useful when working with international servers or APIs.

  4. 4

    Get the current timestamp

    Click the "Now" button to instantly see the current Unix timestamp. Useful for generating timestamps to use in code or database queries.

  5. 5

    Copy the result

    Use the copy button next to any result to copy it to your clipboard for use in your code, SQL queries, or API calls.

Common Uses for a Timestamp Converter

Debugging Server Logs

Server logs often show Unix timestamps. Convert them instantly to understand exactly when an event occurred in your local time.

Database Queries

SQL databases store timestamps as integers. Convert between human dates and Unix timestamps to write precise date-range queries.

API Development

Many REST APIs return dates as Unix timestamps. Convert them to verify the values and understand their meaning during development.

Data Analysis

Spreadsheets and data pipelines often require Unix timestamps. Convert dates to timestamps for data import/export workflows.

Security Analysis

JWT tokens, SSL certificates, and OAuth tokens include expiry times as Unix timestamps. Decode them to see when they expire.

Cross-Timezone Scheduling

Convert a UTC timestamp to your local timezone to understand when a scheduled job or event will run in your region.

Frequently Asked Questions

What is a Unix timestamp?
A Unix timestamp is an integer representing the number of seconds elapsed since January 1, 1970, 00:00:00 UTC (the Unix Epoch). It is timezone-independent and is the standard for storing time in most programming environments.
What is the difference between seconds and milliseconds timestamps?
Traditional Unix timestamps are in seconds (10 digits, e.g. 1700000000). JavaScript and many modern APIs use milliseconds (13 digits, e.g. 1700000000000). Our tool auto-detects which one you entered.
What is the Year 2038 problem?
On January 19, 2038, 32-bit systems storing Unix time as a signed 32-bit integer will overflow. Modern systems use 64-bit integers, which can represent dates hundreds of billions of years into the future.
How do I get the current Unix timestamp in code?
JavaScript: Math.floor(Date.now() / 1000) for seconds, or Date.now() for milliseconds. Python: import time; int(time.time()). PHP: time(). MySQL: UNIX_TIMESTAMP(). PostgreSQL: EXTRACT(EPOCH FROM NOW()).
What is epoch time in milliseconds vs seconds?
Epoch in seconds is the number of whole seconds since Jan 1, 1970. Epoch in milliseconds is 1000× larger and provides sub-second precision. JavaScript dates use milliseconds by default.

Unix Timestamp Quick Reference

Key timestamps: Unix Epoch = 0 (Jan 1, 1970). One hour = 3,600 seconds. One day = 86,400 seconds. One week = 604,800 seconds. One year ≈ 31,536,000 seconds. Y2K38 overflow = 2,147,483,647 (Jan 19, 2038 for 32-bit systems).
