What is a Unix timestamp?
A Unix timestamp represents the number of seconds that have passed since January 1, 1970, 00:00:00 UTC. Some systems use milliseconds instead of seconds. This tool supports both formats and can automatically detect common timestamp values.
About Timestamp Converter
Convert Unix timestamps into readable dates and times, or convert dates and times back into Unix timestamps with the free Timestamp Converter from URLSigma.
Whether you are a developer debugging an application, working with APIs, analyzing logs, or simply need to understand a Unix timestamp, this online tool makes timestamp conversion fast and straightforward.
What Is a Unix Timestamp?
A Unix timestamp is a numerical representation of a specific point in time. It traditionally represents the number of seconds that have passed since January 1, 1970, at 00:00:00 UTC, also known as the Unix epoch.
For example, a timestamp such as:
1710000000
can be converted into a human-readable date and time.
Many modern systems also use Unix timestamps in milliseconds, especially in JavaScript applications and web development. The URLSigma Timestamp Converter supports both seconds and milliseconds.
Convert Unix Timestamps to Dates
Use the Timestamp → Date converter to transform a numeric Unix timestamp into a readable date and time.
The tool supports:
- Unix timestamps in seconds
- Unix timestamps in milliseconds
- Automatic timestamp unit detection
- Local time conversion
- UTC conversion
- ISO 8601 date formatting
Simply enter your timestamp, select the appropriate unit, and click Convert Timestamp. The tool will display the corresponding date and time along with additional timestamp formats.
Convert Dates to Unix Timestamps
You can also convert a specific date and time into Unix timestamp formats.
Enter:
- The date
- The time
- Your preferred input timezone
The tool then generates:
- Unix timestamp in seconds
- Unix timestamp in milliseconds
- ISO 8601 format
This is particularly useful when working with databases, APIs, programming languages, and systems that use Unix epoch time.
Seconds vs. Milliseconds
One of the most common problems when working with timestamps is confusing seconds and milliseconds.
A Unix timestamp in seconds generally looks like:
1710000000
A Unix timestamp in milliseconds generally looks like:
1710000000000
The Timestamp Converter can automatically detect common timestamp formats, helping you avoid conversion errors when working with different applications and development environments.
Local Time and UTC Support
Timestamp data is commonly stored and processed in UTC, while users often need to view it in their own local timezone.
URLSigma’s Timestamp Converter lets you choose between:
- Your Local Time — Displays the converted timestamp using your device’s local timezone.
- UTC — Displays the timestamp in Coordinated Universal Time.
This makes the tool useful for debugging applications, comparing international event times, and analyzing server logs.
ISO 8601 Date Conversion
The tool also provides dates in the ISO 8601 format, a widely used international date and time standard.
ISO 8601 dates are commonly used in:
- APIs
- JSON data
- Databases
- Web applications
- Software development
- Data exchange systems
A typical ISO 8601 timestamp looks like:
2024-03-09T16:00:00.000Z
This standardized format makes dates easier to exchange between different systems and programming environments.

Frequently Asked Questions
What is a timestamp converter?
A timestamp converter is an online tool that converts Unix timestamps into readable dates and times or converts dates and times into Unix timestamp values.
What is a Unix timestamp?
A Unix timestamp represents the number of seconds that have passed since January 1, 1970, at 00:00:00 UTC. Some systems use milliseconds instead of seconds.
Can I convert milliseconds to a date?
Yes. The URLSigma Timestamp Converter supports Unix timestamps in milliseconds as well as seconds.
How do I convert a date into a Unix timestamp?
Select the date, enter the time, choose the appropriate timezone, and use the date-to-timestamp conversion option to generate Unix timestamp values.
What is the difference between Unix time and UTC?
Unix time is a numerical value representing a moment in time relative to the Unix epoch. UTC is a global time standard used to represent and coordinate dates and times.
What is an ISO 8601 timestamp?
ISO 8601 is an internationally recognized date and time format commonly used in APIs, software applications, databases, and data exchange.
