Unix Timestamp Explained

A Unix timestamp is a way of representing time as the number of seconds that have passed since January 1, 1970 UTC. It is widely used in software, APIs, logs, and databases because it is consistent and machine-friendly.

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

A timestamp converter helps turn raw Unix values into readable dates and times, and vice versa.
