Accepted Answer

There will be almost no difference in the local time between Delhi and Bengaluru. Time on Earth is determined by longitude, not latitude. Longitudes are imaginary lines running from the North Pole to the South Pole, and as the Earth rotates, these lines pass under the sun. Places on the same longitu...
