I really don't like thinking about time these days. As I've gotten older time feels like it slips away faster. Time to me is a sad thing to think about. At some point you reach an age where those who were adults long before you are now elderly and leaving the world. One sad passing after another hits you and you have to carry that sadness and loss until it's your turn to leave. As for fiction time can be a fascinating topic. You can go in so many directions.
It truly is sad how fast time goes. One day we will really be gone. That's why we need to enjoy the time we have now. We need to forgive those with whom we are angry. Hold those close to us to our hearts and let them know that we love them. Treat ourselves and others the way we want to be treated. Because there's no time left. There's only now and NOW is the only thing that is real.
