Birth time confirmation request

[Jayanth]

Hello fellow Jyotish lovers,

I am Jayanth Koundinya. Currently, I am residing in Germany. I have a strange confusion. I have got my birth time rectified from three Jyotishis and also confirmed it from the Hospital. Surprisingly, I have been given three separate times. Can anyone please spare some time to take a look at it?
Location: Bangalore, Karnataka, India.
Date: 30th May 1990
Time: 22:15
Times given by Astrologers- 22:07, 21:52 and 22:19.
Events: I had a massive Typhoid fever which resulted in coma in March-April 1999. Apart from that, no life changing events.

Thanks in advance guys!
Cheers!
