Unix timestamps are the standard time representation in POSIX systems (IEEE Std 1003.1) and are used by virtually every database, logging system, and API. The upcoming Year 2038 problem, where 32-bit timestamps overflow, affects an estimated 2+ billion embedded devices worldwide (IEEE Spectrum).

Unix timestamps are used by 95% of web APIs for date handling. According to W3C, epoch-based time is the standard because it's timezone-independent and easy to compare.
What is a Unix timestamp?
A Unix timestamp (epoch time) is the number of seconds that have elapsed since January 1, 1970, at 00:00:00 UTC. It's widely used in computing for representing dates.
How do I convert timestamp to date?
Enter the Unix timestamp and click 'Convert'. The tool shows the date and time in multiple formats and timezones.
How do I convert date to timestamp?
Use the date picker to select a date and time, and the tool instantly shows the corresponding Unix timestamp.
What's the difference between seconds and milliseconds?
Some systems use milliseconds (13 digits) instead of seconds (10 digits). The tool auto-detects and converts between both formats.
Does this support timezones?
Yes! The converter shows timestamps in UTC and your local timezone. You can also convert to specific timezones.
