What is TIMESTAMP?

A TIMESTAMP is a data type used to store a specific point in time, typically including both date and time components. It often includes fractions of a second (milliseconds or microseconds) for greater precision. It is very common for databases to have a timestamp that automatically updates when a row is updated.
