     What is the date and standard time in Paris, longitude 01 15\'15\"E of Greenwich, when it is in Ottawa, longitude 73°53\'30\"W of Greenwich, 23h45m of April 30, 2006?  
  
  Solution
To simplify 3600 has a time difference of 24 X 60 min. So 1 degree will have a time difference of 24X60 /360= 4 min.
Now when we move towards west to east the time will be added
So total distance from west to east = 73053\'30\'\' + 01015\'15\'\' = 7508\'\'45\'
Now,
750 = 75X4 = 300 minutes
8\' = 8 X 4 = 24 seconds
45\' = 3 second
Total 5h0m27s
So Paris is 5 hours and 27 seconds ahead of Ottawa
Time of Paris is 23h45m + 5h27s - 24h = 4h45m27s
And date will also change that is
1 may 2006
So the time in Paris is 4h45m27s and date 1st of May 2006
