About the Unix Timestamp
Convert Unix timestamps to readable dates and back, with a live clock of the current epoch time. A free, private converter for log analysis and API debugging - every conversion happens instantly in your browser.
Unix timestamps — seconds or milliseconds since January 1, 1970 — are the standard way databases, logs, and APIs represent time. They are compact and timezone-neutral, but completely unreadable to humans, so converting back and forth is a constant task during debugging and log analysis.
See the current timestamp ticking live, convert any epoch value to a human-readable date in your timezone, or go the other way from a date picker. Includes millisecond and second precision.
Use cases and examples
Read log lines during an incident: convert the epoch at the error to local time and correlate with other events.
Spot the seconds-versus-milliseconds bug instantly - a 13-digit value where 10 digits was expected.
Set expiry times for tokens and caches by computing the exact future timestamp.
How to use
- Read the live current timestamp at the top of the page.
- Paste an epoch value to convert it to a readable date and time.
- Or pick a date and time to get its Unix timestamp.
- Note whether your value is in seconds or milliseconds.
Frequently Asked Questions
How do I know if a timestamp is in seconds or milliseconds? ▾
Count the digits: 10 digits means seconds, 13 means milliseconds. A 13-digit value used as seconds would be a date tens of thousands of years in the future, which is a common bug.
What timezone does the conversion use? ▾
The readable output uses your browser local timezone. The timestamp itself is timezone-independent — it always represents the same instant worldwide.
