Question

What is indian standard time and its inportance to our daily life

Answer 1

the time in each country is different as the longitudes decide the time of each country..
so India also has its own time
each longitude has 4 mins difference between them therefore we also see that there are many longitudes passing a country so therefore there will be different times in a country . it would create confusion and there will be a harm to our working schedules. so each country has its own time which would be commonly accepted all over the country and the longitude which passes in the middle of a place if a country that places time is accepted countrywide for ease of schedule
