UTC−05:00 takes in Colombia (which has been established as being
Humbertin's point of origin) and Ecuador. (or are people going to say it's
UTC+05:00 which takes in Pakistan

)
Since you claim that this guy Humbertin is from Colombia, isn't that evidence that webtricks and him are not the same persons? I see that webtricks is active in Indian local board has few posts in Hindu (I guess).
Somehow I doubt that webtricks is writing there as part of his disguise.
