When was the first time humans realized time zones and their differences? What lead to that discovery? And how did they react to it?

Time zones are entirely arbitrary and made up.

However; you can read more detail [in this discussion of time zones!] (http://www.reddit.com/r/AskHistorians/comments/qh4i1/how_long_have_people_known_about_time_zones_and/)

Always a fascinating topic if you ask me!
