Grandpa was waiting impatiently in the Waiting area of Yale Hospital in Connecticut US. It was past midnight. His second daughter was giving birth to her first child (C-section).
His son-in-law came out of OR and told him happily that he is Grandpa again with a baby boy born just now. Then he went back to the OR.
Happy Grandpa called Grandma (strict instructions!). She was very happy.
"What time?" she asked
Grandpa took a quick look at the Clock on the Waiting room wall and said:
"2:50 at night-- umm early morning November 6 2016"
After their conversation ended he quickly called her again and said:
"I am sorry. The correct time should be 1:50 dear"
After that conversation ended he looked at the wall clock again and -- you guessed it-- called her again
" I am sorry dear. It should be 1:10 AM actually"
What is going on here??
Note : Grandpa did not talk to anyone during the time he made the calls except Grandma.
