May I just offer you some thoughts on the horoscope you mentioned, For birth time rectification, you need more information on events in the person's life. I am mainly concentrating on the loss of mother and effects of Mars Mercury and the Moon.

Taking Cancer as Lagna, firstly notice that the Lagna is in the 4th pada of Aashleshaa Nakshatra, which is very inauspicious as it is in Gandant status (junction of water/fire signs,, cancer/leo). During Mars and Mercury period, native lost his mother, Mercury is 12L and 3L, hence malefic for Lagna. Mercury is in Nakshatra of Jupiter, who is placed in the 2H (Maarak powers) Mars is Yog Kaaraka for this Lagna, but is very weak (2deg Libra) placed in an enemy sign (Venus). Venus is in 2h from Mars (Maarak effect)

Mars and Mercury are also temporary and permanent enemies - therefore they are bitter enemies. All this is crippling Mars and it is unable to give good results. Both Mars and Mercury are placed in 4th house, which is a Moksha house. Moon is in 7H capricorn, whose lord Shani is weak, Moon in Dhanishthaa Nakshatra, whose lord and sub-lord is Mars, (very much weaken as explained above)

In Bhaav Chaalit chart, Jupiter aspects Moon but Jupiter is 6HL and 12HL. The 4H is badly afflicted, Maarak 2HL Sun, Mercury 3HL and 12HL and Shani 7HL and 8HL. In Navamsha, Moon is with Ketu and Sun in the 6th house, with Mars, the Nakshatra Lord of Moon placed in 8H. Shani the depositor of Moon is placed in the 5H, which is 12th house from Moon. Hope that answers some of your questions..
