Rectification / Adjustment in birth time - its necessity?

[Guest guest]

Namaste,

 

All horoscopes are casted on the strength of time indicated by available clock

time on the eve of ones birth / event.

 

In addition to the above,multi various Astrological siddhanta / principle

parameters adopted by different Astrological groups.

 

Further Astrologers' capacity to recollect what they have read and learnt are

also vary from individuals to individual.

 

All the above factors play a pivotal role in predictions;it is quite natural no

universal true congruent predictions are possible.

 

Therefore Astrologers resort to adjustment in birth time to suit their

conveniences, which they term it as rectification of birth time.

 

Comments from experienced learned are welcomed.
