ok actually here it is "time zones were first establised in 1882 with the coming of the railroads. Why did railroads make time zones necessary?
It's for science again!
I'LL ALWAYS LOVE YA!!!

because they needed ot be able to schedual trains that traveled far enough that local time where they originated and local time where they went were in sync.
also to keep two trains from being on the same piece of track at the same time (a bad thing)

Railroad schedules were difficult because each station kept its own time. Now, if every station set it time such that when the sun reached its zenith at noontime, which was basically the case, you had to change time everytime you left one station to be ready for the next station. The railroads championed time zones to reduce this confused situation to a managable one, since each time zone was approximately the distance you would travel cross-country in one day.

Before the establishment of uniforn time zones, everywhere in the country ran on local sun time. This made train scheduling a virtual impossibility because clocks would have had to be continuously changed as you moved east or west. The rate of clock change would also have been dependent on the speed of the train.
