Most probably not. 'A Time for Heaven' is often classified as a work of fiction. Usually, such titles are crafted from the imagination of the author or screenwriter to tell an interesting tale rather than being based on real events.
I'm not sure specifically as there could be many different interpretations. It might be a personal or fictional account related to a time that feels like heaven, perhaps a special moment in someone's life, like a beautiful vacation or a deeply spiritual experience.
