Why timestamps are useful
- Easy for computers to compare and sort
- Common across programming languages and APIs
- Helpful for logs, events, and scheduling
Seconds vs milliseconds
Some systems store Unix time in seconds, such as 1700000000.
Others use milliseconds, such as 1700000000000.
Where you see them
- Server logs
- API responses
- Databases
- Analytics and tracking systems
Converting timestamps
