I am in a very big dilema regarding my birth details and my chart.I have been told that my birth time is aroud 7:10(we never do charts at our place) and that was the time i gave while asking for my career and marriage details in this community
but now my grandmother who was there at the time of my birth has told me that my time of birth is around 7:30 to 7:50a.m...Is there any way where in i can know the exact time of my birth and does this time change matter for reading the chart?Its just so confusing!! 
is there a way to know the right time?My details:-
