What is Unix Timestamp Converter – Epoch Time Converter Free?
A Unix timestamp (also called Epoch time) is the number of seconds that have elapsed since January 1, 1970, 00:00:00 UTC. It is timezone-independent and widely used in programming, databases, and APIs. Our Timestamp Converter shows the current live Unix timestamp and lets you convert timestamps to UTC, local time, ISO 8601, and relative time — and convert any date/time back to a Unix timestamp in seconds or milliseconds.

Frequently Asked Questions
What is a Unix timestamp?
A Unix timestamp (also called Epoch time) is the number of seconds that have elapsed since January 1, 1970, 00:00:00 UTC. It is timezone-independent and widely used in programming and databases.
What is the difference between seconds and milliseconds?
Unix timestamps in seconds are typically 10 digits (e.g. 1717200000). Timestamps in milliseconds are 13 digits (e.g. 1717200000000). JavaScript's Date.now() returns milliseconds.
How do I get the current Unix timestamp?
The 'Current Unix Timestamp' shown at the top updates every second. You can also click 'Use Now' to load it into the converter. In code: Math.floor(Date.now() / 1000) in JavaScript.
Does this work with negative timestamps?
Yes. Negative Unix timestamps represent dates before January 1, 1970.
Is my data sent to a server?
No. All conversions run entirely in your browser using JavaScript's built-in Date object.
How do I tell if a timestamp is in seconds or milliseconds?
Timestamps in seconds are typically 10 digits (e.g. 1717200000). Timestamps in milliseconds are 13 digits (e.g. 1717200000000). The tool auto-detects which format you entered.
How do I get the current timestamp in code?
JavaScript: Math.floor(Date.now() / 1000). Python: import time; int(time.time()). PHP: time(). Unix shell: date +%s.
Does this support negative timestamps?
Yes. Negative timestamps represent dates before January 1, 1970 (e.g. -1 = December 31, 1969 23:59:59 UTC).
