Question
Why do we need standard time?

Answer

  1. The local time of places which are on different meridian are bound to differ and bound to create confusion and inconvenience.
  2. For example, it will be difficult to prepare a time table for trains which cross several longitude.
  3. In India for instance there will be difference of about 1 hour and 45 minutes in the local time of Dwarka in Gujarat and Dibrugarh in Assam.
  4. Therefore, it is necessary to adopt local time of some central meridian of a country as the standard time for the country.
