How can you say that the use of ‘Local Time’ is very inconvenient nowadays in practical life?
उत्तर
Use of Local time is very inconvenient nowadays in practical life because if we have to travel through many countries, it will be convenient to us to follow one particular standard time, according to which we can set our watches with respect to a particular country and its standard time with reference to Greenwich or Prime Meridian (0° Longitude) to bring about international uniformity. This is known as Greenwich Mean Time (GMT). The Indian Standard time is 5 hrs 30 minutes ahead of GMT.
