Answers
Answer:
The relation between longitude and time is 4 minutes/degree longitude, counting from the 0degree meridian at Greenwich ( say, London). therefore Kolkata being 88.5 degrees East of the 0-degree meridian and New York being the 74- degree West of 0-degree meridian, the difference is 88.5+74=162.5 degrees, and, hence, in time scale162.5x4=649.6 min= 10 hrs. 49 min ( seconds ignored). Hence, while Kolkata is at 9 AM of 1st January 2009, New York is behind by 10hrs. 49 min. ie. 1hr 49 min to attain midnight between 31st December 2008 and 1st January 2009.
Thus, the local time of New York was 10 hr11min (P.M.) of 31st December 2008.

Answer:
10:11pm of 31st December 2008 is the local time of New York.

Difference in longitude when they are in different hemisphere = (east+west) 88.5° +74° =162.5°
1° longitude causes a time difference of = 4 minutes
162.5° longitude causes a time difference of = 4 x 162.5° = 650min =10 hours 50mins
Since the place is in the west time gets subtracted= 9:00- 10:50
=10:10 pm the previous day
= 10:10 pm on 31st December 2008
