Can my birth chart(from 2) determined by seeing my palm?

As i don't know my exact Birth time(i just know between 4:00pm to 4:30pm) is it possible to determined which birth chart(2 birth chart shows within that time) could be mine by seeing my palm?
my birth detail is:
Mehedi Hussain Sshoibal
Birth date- 29 November,1976
Birth time- 4:00pm to 4:30pm
Birth place- Mymensingh,Bangladesh
Latitude: 24.45N, Longitude: 90.24E

one birth chart shows:(N.C.Lahiri)
Jupiter(lagna) in 1st house in Taurus,
Saturn in 3rd house in cancer,
Rahu in 6th house in Libra,
Sun,Mercury,Mars in 7th house in Scorpio
Venus in 8th house in Sagittarius,
Moon in 10th house in Aquarius, and
Ketu in 12 house in Aries.

other birth chart shows:(N.C.Lahiri)
Ketu(lagna) in 1st house in Aries,
Jupiter in 2nd house in Taurus
Saturn in 4rd house in cancer,
Rahu in 7th house in Libra,
Sun,Mercury,Mars in 8th house in Scorpio
Venus in 9th house in Sagittarius,and
Moon in 11th house in Aquarius,

but interestingly in the web at vedic-astrology.net i found my birth chart same even in both time 4:00pm or 4:30 pm as follows:
Jupiter+Ketu in 1st house in Taurus,
Saturn in 4rd house in Leo,
Rahu in 7th house in Scorpio,
Sun,Mercury,Mars in 8th house in Sagittarius
Venus in 9th house in Capricorn,and
Moon in 11th house in Pisces,

so far i studied the meaning of different planets position in different houses. i found the description of Jupiter in 1st house,Venus in 9th house and Moon in 11th house suits me most..
i would be so happy if someone can help me which birth chart could be mine by watching my palm and if also can get gemstone recommendation. 2 astrologers suggested me to wear Blue Sapphire and other 2 astrologers suggested me to wear Yellow Sapphire.i am little confused now about that ! i have already order for Blue Sapphire, now wondering should i wear!
