Sobre esta herramienta
Unix time counts seconds since 1 January 1970 (the epoch), and it shows up everywhere in logs, APIs and databases. This tool shows the current timestamp updating live, converts a timestamp in seconds or milliseconds into your local time and UTC, and converts any date and time back into a Unix timestamp. All the maths happens in your browser.
Cómo usarla
- Paste a timestamp and pick whether it is in seconds or milliseconds to see the matching date.
- Or pick a date and time to get its Unix timestamp.
- Watch the live counter at the top for the current timestamp right now.
Preguntas frecuentes
What is Unix time?
The number of seconds that have passed since 1 January 1970, 00:00:00 UTC (the "epoch"). It is the standard way computers store and compare points in time.
Seconds or milliseconds?
Unix timestamps are traditionally in seconds. Many APIs and JavaScript itself use milliseconds instead - if your numbers look 1000 times too large, switch the unit selector.
Does this account for time zones?
A Unix timestamp itself has no time zone - it is a single point in time. This tool shows that point converted to both your local time zone and UTC so you can compare them.
