Question

If every state follows its local time then what
problems would rise?

Answer 1

There are many countries with multiple time zones. The US has three time zones the Easter time zone, middle America and Pacific Time Zone. Same with countries such as Russia which covers over 12 time zones.
However, there are large countries such as China which rely on only 1 time zones, despite the huge size.
Apart from simple confusion within states, multiple time zones will unnecessarily increases costs associated with multiple time zones including TV programs, National Schedules, Airports and Trains which will need to heavily invest in upgrading all their systems to meet the new regulations for every State.
This will be a huge wastage of government funds and will also create divisions among different states in the country.
