We’re back on Standard Time now. That means you drive home from work in the dark. Hawaii and Arizona never left Standard time, so they don’t have to mess with their clocks. Some of us liked it better before the world began organizing time. Some of us right here at Critical Pages, for example, get suicidal when twilight creeps up in the middle of the afternoon.
But suicide isn’t necessary. A study by professors Paul Fischbeck, at Carnegie Mellon University, and others, found that after the time change pedestrians walking during evening rush hour are nearly three times more likely to be struck and killed by cars than before the change. Which is another reason we don’t like messing with the clock.
Fooling with clocks is always lethal. “The Monday and Tuesday after moving the clocks ahead one hour in March is associated with a 10 percent increase in the risk of having a heart attack,” says Martin Young. Professor Young is in the Division of Cardiovascular Disease at the University of Alabama (Birmingham), so he probably knows what he’s talking about. Furthermore, he says, “The opposite is true when falling back in October. This risk decreases by about 10 percent.”
In the old days — we’re thinking of the 1800’s here — every town and city set its own time. When the sun was directly overhead, that was twelve noon, so they set the big town clock to twelve and everyone in town set their timepieces by the local clock. That worked fine until railroads became an important feature of life. British railroads switched from local time to the time set by the British observatory at Greenwich, hence what we call Greenwich Mean Time. And by most folks it was called Railway Time. During the 1800’s the British and the French were competing to set standards — standards for weights, lengths, time, and where the zero meridian should be placed. The French wanted it to run through Paris. The British won out, so it runs through Greenwich. On the other hand, the French won on length and had the final word on how long a meter was.
But we digress, as usual. The illustration for this post is a still from the 1923 movie “Safety Last” starring Harold Lloyd. It’s an example of how dangerous it is to mess with clocks. Check it out — if you have a few minutes of Standard Time.
