## Definition

a record that shows the exact date and time when something happened. You see it on messages, files, and videos to know when they were made.

For teachers: a recorded date and time indicating when an event occurred or data was created or modified. It is often attached automatically to digital files, messages, or transactions to establish sequence and authenticity.

## Examples
