"For a person whose past,present and future are the same" from Dhammapada

With reference to the title of the question, I would like to know if the person blessed or under a curse if for him the past, present, and future are the same? If by unlawful acts he is elevated to a higher position when these three positions are better. He wants such a condition to perpetuate and go on. If he is downgraded for his lawful acts, his downfall is usually bitter for him. How to analyze the situations?
