In KP method, the number chart has to be prepared by the KP astrologer at his place and at his time, not the client’s time. Any KP follower will do this.
Regarding the difference of time, what I observed is, the time showing is GMT. The GMT + 5.30 gives IST. This is a fundamental thing, an astrologer should know, otherwise the clients may understand that the astrologer doesn’t know KP and he is bluffing them and they lose faith in astrology as a whole.
I clarified your doubts and will give my reading in the next mail.
