How did the railroads change the way Americans told time?

The underlying cause of confusion was simply that the United States had no time standard. Each town or city would keep its own solar time, setting clocks so noon was when the sun was directly overhead. ... So it's fair to say the American railroads changed the way the entire planet told time.

the most famous of all the units fighting in cuba, the "rough riders" was the name given to the first u.s. volunteer cavalry under the leadership of theodore roosevelt. roosevelt resigned his position as assistant secretary of the navy in may 1898 to join the volunteer cavalry. the original plan for this unit called for filling it with men from the indian territory, new mexico, arizona, and oklahoma. however, once roosevelt joined the group, it quickly became the place for a mix of troops ranging from ivy league athletes to glee-club singers to texas rangers and indians.
