Frequently Asked Questions
Seconds or milliseconds?
Unix time is defined in seconds, and a current value is 10 digits. JavaScript works in milliseconds, giving 13 digits. If your number is 13 digits long, switch the unit selector to milliseconds.
What timezone are the results in?
The tool shows local time (from your device), UTC, ISO 8601, and Indian Standard Time side by side. The timestamp itself is timezone-independent — it is the same instant everywhere.
What is the year 2038 problem?
Systems storing Unix time in a signed 32-bit integer overflow on 19 January 2038. Modern platforms use 64-bit values, which push the limit well past the lifetime of the universe.
Does Unix time account for leap seconds?
No. It counts as though every day has exactly 86,400 seconds, so it drifts from true astronomical time by the accumulated leap seconds — currently 27.
