Definition of time as defined in physics?

In physics, time is defined as a measurable period during which an event occurs or an object exists. It is a fundamental quantity that is used to sequence events, to compare the durations of events and the intervals between them, and to quantify rates of change. Time is typically measured in seconds, minutes, hours, days, years, etc., and is considered to be one of the four dimensions of spacetime, along with length, width, and height.

Time is one of the fundamental dimensions of the universe, along with length and mass. It is the measure of the duration of events and the intervals between them. In physics, time is often defined as the fourth dimension, after the three spatial dimensions of length, width, and height.

Time is a scalar quantity, meaning that it has no direction. It can be positive or negative, and it can be measured in a variety of units, such as seconds, minutes, hours, days, years, and centuries.

The concept of time is closely related to the concept of space. In fact, some physicists believe that time and space are not separate entities, but rather are part of a single continuum called spacetime.

Time is a fundamental part of our universe, and it plays a role in all physical processes. It is the measure of our lives, and it is the fabric of the universe itself.
