Justin Graham, writing for the Evansville Courier Press, has a column explaining why, as a matter of geometry, it’s ridiculous for Indiana to be on Eastern Time. If you have 24 equal, one hour time zones and if the time zones use Greenwich England (for arbitrary historical reasons) as the starting point, then the boundary between Eastern and Central should be somewhere near Mansfield, Ohio.
But, I might suggest that we’re getting close to the time when it’s appropriate to do without time zones entirely. We’ve been adjusting our relationship to our clocks and the time of day as technology progresses. Before railroads and telegraphs, there was no need or ability to coordinate your efforts with any great precision with people who were very distant from you. Communications couldn’t travel much faster than the sun. With railroads and telegraphs, the ability and need increased a bit; but there was no need to coordinate much beyond the 750 mile width of a time zone.
But now, we are becoming increasingly connected with those around the world. It’s not at all unusual to work with people around the world. It might be time to put the world on a single standard time. The fact that Terre Haute is part of a time zone that should end at Mansfield shows we’re no longer too concerned with having 12:00 hours associated with the sun being directly overhead. In for a penny, in for a pound, maybe we should all go to Coordinated Universal Time.
