How does Bierce develop the theme "time can be subjective"?

Answer: "An ocurrence at Owl Creek Bridge" by Ambrose Bierce is the story of Peyton Farquhar a southern farmer who is about to be hanged by the Union army for trying to destroy the railroad bridge at Owl Creek.

Explanation: In the sory before mentioned Bierce uses an intricated framework to advance the theme of time. He distorts the reader sense of time by telling at the end of the story that Farquhar imagined his scape in a few seconds before he died even though the scape takes a long time in the narrative. Bierce also stresses that time is subjective and phenomenal, specially during times of mental or emotional harship.
