The Washington Post recently published an article on a proposal by an economist and professor of physics and astronomy to create a single time zone for the entire planet. Those of us who travel regularly know that time zones are a hassle because adjusting sleep cycles is rarely easy. Their plan is to use UTC (basically, Greenwich Mean Time) as the planet’s time zone.
Putting the planet on a single time zone wouldn’t solve this particular problem unless we decided to ignore our circadian rhythm, i.e. rising around sunrise and going to sleep in the dark. I would imagine the Japanese and Chinese would be pissed as they would arise around sunset and go to sleep around sunrise. However, China already sees an advantage in having a single time zone. The whole country is on one time zone, basically +12 UTC. Perhaps this helps bind them together as a nation but for those in the far eastern or western parts of the country it must seem weird. It’s particularly weird when you move from eastern China into far eastern Russia. You jump two time zones to the east! China is about the size of the United States, so it would be like everyone in the United States being on Central Time.
I don’t think a law can easily break our circadian rhythms, which is why so many of us groan when entering daylight savings time. It feels unnatural because it is unnatural, at least in early March. But it’s less unnatural if you are lower in latitude and you happen to live close to a longitudinal meridian evenly divisible by 15. For those of us on the edge of a time zone, life seems to either start too early or end too late.
I certainly noticed it last year when we moved to Massachusetts, so much so that I blogged about it. Spain is considering changing its time zone to something more natural; it has been on central European time since World War Two. Spaniards get nearly an hour less sleep because of their unnatural time zone and unsurprisingly tend to be late to bed, at least by their clocks. Siestas are a way of compensating for their unnatural time zone.
Airlines already use UTC for flight schedules. This makes a lot of sense since pilots are frequently changing time zones. Of course they do take into account the sleeping habits of the people they are moving, which is why more flights happen during the daytime than at night. Laws vary so widely across the world (North Korea recently decided to change their time zone by half an hour) that some sort of time uniformity sounds desirable. As a practical matter geography often gets in the way, with Indiana being a case in point, as it is split between eastern and central time. No system is perfect.
Living in Massachusetts the time really feels “off”. I’m not alone, which is why there is a proposal to put New England on Atlantic Time, or -4 UTC instead of Eastern Time (-5 UTC). States can set their own time zones. However, here in New England it doesn’t make much sense for each state to go it alone, as our states tend to be small. It only makes sense if everyone adopts it. Rhode Island state Rep. Blake Filippi has proposed a bill to do just this, but only if Massachusetts also adopts it. He’s hoping it would coax the other New England states to go along.
My suspicion is that if Massachusetts embraced it, the other states here in New England would too. The possible exception would be Connecticut and that’s because it has so many commuters going into New York City everyday. As “off” as the time feels here in Massachusetts where the sun rises as early as 5:12 AM where I live and sets as early as 4:17 PM, it’s even worse the further east and north you go. To take an extreme example, the sunrise in Lubec, Maine starts as early as 4:41 AM and sets as early as 3:47 PM.
This is not a big deal in more extreme northern latitudes, but New England is simply not as far north as most of Europe. We are roughly at the latitude of Northern Spain. Being on Eastern Time is purely a political decision. Going to Atlantic Time for us pushed way north and east on the U.S. eastern seaboard would make a lot of sense and would feel more natural. We’d get later sunsets in the summer and more daylight in the winter when it is greatly needed.
So here’s hoping. Maybe I’ll write my state legislators. Winter is dark and dreary enough around here. There’s no point in making it more so. So I say let’s skip the idea of a worldwide time zone and make tweaks to the time zone maps we already use to make them fairer to actual human beings. As for us in New England, we have already suffered enough. Put us on Atlantic Time!
