The Twenty Four forms of Prakrithi is described and then the Twenty Fifth form is said to be TIME. Bhagavatham says that Jeeva forgets its true nature due to ignorance and sees the body as the Atma, because of Kalam (Time). Ahamkaram (Ego) causes the doership and then creates forgetfulness of our true nature and fear of death. Here Time is described as the cause of destruction.

Time is divided into two forms – the first form destabilizes Prakrithi and this leads to creation. The second form leads to destruction and fear. Prakrithi was dissolved in its balanced state in the Purusha before creation. Whatever caused the imbalance in the Trigunas is called Time or Lord Himself.

That means, the Lord is your inner Self and externally the same Lord appears as Time. Chaitanyam with Avidya (Jeeva) and Chaitanyam with Vidya (Easwaran) are ONE and the same and is called Purusha which is the Twentyfifth.

Note – in continuation to the definition of Prakrithi, Time is defined here as the force that changes an equilibrium state. We can take it as the duration between two events. The first event that creates a new imbalanced state and the second event that destroys it. That is why we say, anything that is born, is bound to die too.
