Hi brother @JLim
I got Puyi's chart from 千里命稿 written by 韦千里.
I don't know how Master 韦千里 obtained Puyi's birth time  but; i do know that Mr. 韦千里 was one of the most recognized practitioners of his time. (1911-1988)
The rich and powerful all wanted their charts read by him.

 Here is his interpretation of Puyi's chart.

丙午  庚寅  壬午  丙午

有以宣统这命垂询者。余曰。满盘是财。偏枯之局。本无足贵。其为失国之君。良以身不任财。弃命而从之故耳。惟二午暗邀合宫之未。示藏己土正官。即命理约言所谓暗合格。是乃贵徵。故出身天潢。贵胄后裔。得继大统。惜行运不济。如壬辰运之犯火。乃从格所大忌。失其自由。任人支配。三十几交癸运。仍虽乐观。三十五以后。己甲午乙。一路东南木火。始堪吐气扬眉。激昂青云。五十五未运为暗合填实。寿终于此。余于庚午秋。得见一命。为丙午甲午壬午丙午。生于夏令。又为四午。合官最力。格局远在宣统之上。想其前程必有可观。乃一福州人。惜已忘其姓氏。兹论宣统命造。忽忆及此君。不胜神往焉。

I think there is one thing important to note. Harry Hussey was a western scholar writing about CiXi.
We don't know his level of understanding Chinese. He could of easily misinterpreted or mistranslated the words of CiXi.
Wheras 韦千里 was a actual native Chinese practitioner that actively gathered and interpreted charts.
