Is “In official history, Shen Rong opened the east gate at night; the novel changed it to opening the west gate at dawn” true?

In the official history, Shen Rong opened the east gate at night, while the novel changed it to opening the west gate at dawn. The Records of the Three Kingdoms records: "Rong, the nephew of Pei, guarded the east gate, opened it at night to let in Cao Cao's troops, and fought with Pei in the city, capturing Pei alive." In Chapter 32 of the Romance of the Three Kingdoms, it is changed to: "At dawn the next day, Shen Rong opened the west gate wide and let Cao's troops in. Xin Pi rode in first, and the soldiers followed, entering Jizhou."
