Time of birth for D-10

[Guest guest]

Dear members,

 

I was using JH for my D10 analysis and when it tells me that my

ascendant will change sign if my birth time is 35 sec later or 9 min

earlier.

 

Now, it is practically impossible to tell whether th birth time was 35

sec later or not.

 

Since the planetary positions chnage if the birth time is changed,

what should I do to find out my correct D-10 ?

 

Thank you.
