The all-time most popular post on this blog, with more than 146,000 views and 99 comments, is “European Date Format” (that is, rendering a date as date/month/year rather than the traditional U.S. month/date/year).
A communication I recently received from Amazon, giving instructions on returning an item to one of its Lockers, made me wonder if I might repeat that post’s success. Here’s what Amazon sent me:
The key is that “21:00.” The traditional American rendition of that time is 9:00 PM. So, I wondered, is there a trend of U.S. adoption of European time format?
For the purposes of this blog, the first question to answer is whether the 24-hour format is indeed a British thing. The answer is a bit mixed. I just read an entertaining free e-book on the subject called Counting Time: A Brief History of the 24-Hour Clock, by Peter Boardman. He recounts how this idea was broached following World War I, was adopted by the British Army and Navy, and was endlessly debated in the House of Lords and the letters pages of The Times in the 1920s and early ’30s. The Lords endorsed the 24-hour clock in 1933 and the BBC experimented with it the following year, but no one seemed to like the idea and it was pretty much dropped till 1964, when the railways and London Transport adopted. Boardman concludes, “Instead of having just one time system, we have two, and they’re both going to be with us indefinitely. ”
The book was published in 2011 and things may have changed in the intervening years, at least according to the responses I got when I asked British people on Twitter if they thought the 24-hour clock was common in the UK. Lynne Murphy said, “Very widespread–and I love it.” Mark Stradling ventured, “Written down, pretty much ubiquitous,” but noted a caveat: “Nobody talks like that, makes you sound like a robot.”
In the United States, the only home of 24-hour time has until now been the military, as one knows from movies where people talk about “Fourteen hundred hours.” But it’s also (not surprisingly) widespread in the computer world, which is presumably where Amazon picked it up.
In sum, I deem the 24-hour clock a Britishism and, in these parts, On the Radar. Let the page views and comments begin.
