 This is an easy-to-use Unix time utility. A tool which allows you to convert Unix time (seconds since Unix epoch, UTC seconds) to a normal date. The other direction from a date to a Unix time is also possible. Dieser Rechner ist auch auf deutsch verfügbar.

What is unix time?

Unix time, or POSIX time, is a system for describing points in time, defined as the number of seconds elapsed since midnight Coordinated Universal Time (UTC) of January 1, 1970, not counting leap seconds. It is widely used not only on Unix-like operating systems but also in many other computing systems. It is neither a linear representation of time nor a true representation of UTC (though it is frequently mistaken for both) as the times it represents are UTC but it has no way of representing UTC leap seconds (e.g. 1998-12-31 23:59:60).

How can i use it?

You can either enter a Unix time value (e.g. 496088259) or a date string (e.g. 2009-01-20 08:17:39) into the upper text field OR you can choose a date using the selector below. Choose your time zone and click the 'convert' button.

What time zone should i use?

This depends on the time you want to convert. If you have for example a Unix time stored on a server which runs in Germany with the correct German time set, then you choose GMT +1, because thats the correct time zone for Germany.
Some examples for time zones:

  • Apia, Upolu Island, Samoa: GMT -11
  • Honolulu, Oahu, Hawaii, United States: GMT -10
  • Anchorage, Alaska, United States: GMT -9
  • Los Angeles, California, United States: GMT −8
