What is time? Is it a physical or mathematical quantity?

Time is a physical quantity that is measured in various units such as seconds, minutes, hours, days, weeks, months, and years. It is a concept that is used to describe the duration or interval between two events. Time is often used in mathematics to measure the rate of change of a given quantity, such as velocity or acceleration. It can also be used to measure the duration of an event, such as the time it takes for a ball to reach the ground after being dropped. Time is an important concept in both physical and mathematical contexts, as it allows us to measure and compare events.
