About Unix Timestamps
Unix time (also known as Epoch time or POSIX time) is a system for describing a point in time. It is the number of seconds that have elapsed since the Unix epoch (00:00:00 UTC on January 1, 1970).
Common Unix Timestamp Examples
| Timestamp | Date (UTC) | Description |
|---|
| 0 | 01/01/1970, 00:00:00 | Unix epoch |
| 946684800 | 01/01/2000, 00:00:00 | Y2K |
| 1609459200 | 01/01/2021, 00:00:00 | Recent date |
| 2147483647 | 01/19/2038, 03:14:07 | Year 2038 limit |
Practical Applications
- Log file analysis and debugging
- Database timestamp conversions
- API development and testing
- System administration tasks
- Data science and analytics
Technical Details
- Timestamps before 1970 are represented as negative numbers
- Most systems use seconds, some use milliseconds (check your system)
- The Year 2038 problem affects 32-bit systems (max timestamp 2147483647)
- Leap seconds are not counted in Unix time
