When was Chairman Mao born (how many minutes and seconds)?

Mao Zedong was born on 1893, on the Gregorian calendar1February 26th.

According to page 1 12 of Bai Baoquan's numerology, Case 6: Study on the numerology pattern in Mao Zedong: The four pillars are Jiaziyue, Ding Youri and Chen Jiazhi of your company. But the author Mr. Bai did not talk about the origin of the date of birth.

The author loves reading fortune-telling books sold in stalls since he was a child. Some of them wrote that Mao Zedong's time column was Guimao, while others were Renyin, but they didn't notice the source of the information. So, I don't know which time is right!
