What is a Unix Timestamp?
A Unix timestamp (also known as epoch time, POSIX time, or Unix epoch) is a way of representing a point in time as a single number. It counts the number of seconds that have elapsed since January 1, 1970, 00:00:00 UTC — a moment known as the Unix epoch.
This system was chosen for the original Unix operating system and has since become the standard time representation in most programming languages, databases, and APIs. Because it is a simple integer, it is easy to store, compare, and transmit.
Unix timestamps are timezone-independent. The same timestamp represents the same instant everywhere in the world. When you convert a timestamp to a local date, the timezone offset is applied during conversion.
Common Timestamps
| Event | Timestamp | Date (UTC) |
|---|---|---|
| Unix Epoch | 0 | January 1, 1970 00:00:00 UTC |
| Year 2000 | 946,684,800 | January 1, 2000 00:00:00 UTC |
| Year 2010 | 1,262,304,000 | January 1, 2010 00:00:00 UTC |
| Year 2020 | 1,577,836,800 | January 1, 2020 00:00:00 UTC |
| Year 2025 | 1,735,689,600 | January 1, 2025 00:00:00 UTC |
| Y2K38 Problem | 2,147,483,647 | January 19, 2038 03:14:07 UTC |

time()Frequently Asked Questions
A Unix timestamp (also called epoch time or POSIX time) is the number of seconds that have elapsed since January 1, 1970 00:00:00 UTC (the Unix epoch). It is a widely used format for tracking time in computing because it is timezone-independent and easy to compare.
The Year 2038 problem (Y2K38) occurs because many systems store Unix timestamps as 32-bit signed integers, which can only represent values up to 2,147,483,647 — corresponding to January 19, 2038 03:14:07 UTC. After this moment, the value would overflow and wrap to a negative number. Modern 64-bit systems are not affected.
No. Unix timestamps always represent seconds since the epoch in UTC. When you convert a timestamp to a local date, the timezone offset is applied during the conversion, but the timestamp itself is timezone-neutral.
