Frequently Asked Questions
What is a Unix timestamp?
A Unix timestamp (or epoch time) is the number of seconds that have elapsed since January 1, 1970 00:00:00 UTC. It is widely used in programming, databases, and APIs to represent points in time as a single number.
What is the difference between seconds and milliseconds timestamps?
A seconds-based timestamp is typically 10 digits (e.g. 1711382400), while a milliseconds-based timestamp is 13 digits (e.g. 1711382400000). JavaScript and Java commonly use milliseconds, while PHP, Python, and Unix systems use seconds.
What is the Year 2038 problem?
The Year 2038 problem occurs because 32-bit systems store Unix timestamps as a signed 32-bit integer, which overflows on January 19, 2038 at 03:14:07 UTC. Modern 64-bit systems are not affected.
Can I convert dates from different timezones?
Yes. This tool lets you select any timezone to see the converted date in that region's local time. Unix timestamps themselves are always in UTC.
Is this timestamp converter private?
Yes. All conversions happen entirely in your browser. No data is sent to any server.
