What is a Unix timestamp?
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. It is the most widely used time representation in computing — used in databases, APIs, logs, and programming languages worldwide.
Common epoch timestamps
| Timestamp | Date | Event |
|---|---|---|
| 0 | Jan 1, 1970 | Unix epoch (the beginning) |
| 1000000000 | Sep 9, 2001 | Billennium |
| 1700000000 | Nov 14, 2023 | 1.7 billion seconds |
| 2000000000 | May 18, 2033 | 2 billion seconds |
| 2147483647 | Jan 19, 2038 | Y2K38 problem (32-bit overflow) |
Frequently Asked Questions
What is the Y2K38 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. Modern systems use 64-bit timestamps, which won't overflow for another 292 billion years.
Are Unix timestamps in seconds or milliseconds?
The standard Unix timestamp is in seconds. However, JavaScript's Date.now() returns milliseconds. This tool auto-detects: if your number is larger than 10^12, it is treated as milliseconds.
