I was on vacation in Hawaii for two weeks, where I got reacquainted with the idea of "island time." On island time, things happen at the relaxed pace of a gentle warm breeze. It's best not to mess with island time -- you'll just harsh your own mellow.
But now the Bush administration wants to mess with all our time, by changing the schedule of when daylight savings time starts and ends. This is supposed to save energy. Which it may well do -- but at the cost of making some our clocks wonky.
(By the way, I'm writing about this by way of putting thoughts together for a CBS LA appearance I'm supposed to do this afternoon.)
Now, as I see it, there are three kinds of clocks we have to worry about, and only one kind is truly vulnerable:
1. Clocks that update themselves. That is, clocks on computers, clocks that get signals from NIST. These can all be reprogrammed. It will cost money, but it's doable, and certainly nowhere near a big deal as the Y2K problem. As long as the programming is done right and on time (ok, a big if), we shouldn't see airplanes landing on top of each other. Certainly services companies (like energy and phone companies) will be highly motivated to make the change, so they don't miss-bill people.
2. Clocks that we update ourselves. In other words, the clock on your old microwave, the clock in your car, and your wristwatch. You'll just have to re-set them on a different day. Big deal. This is a public communications (marketing) problem more than anything else.
3. Clocks that think they know when daylight time starts and ends… but are wrong. This is the biggest problem. There are some clocks now that are hard-coded to flip from standard to daylight time automatically, like some VCRs. These are going to cause people some grief.
The whole idea of time being kept locally is rather arcane anyway. Since so much that we and our machines do these days has to be coordinated with others, the best way to keep good track of time is to get the time from a central time server. Which is what Windows PCs do every time they log in, modern VCRs do when they get a PBS signal (which carries time information), and more and more desk clocks, wall clocks, and wristwatches do when they get a timing signal over the air. (The only issue with self-setting clocks is that some only receive data on the minute and second, to fine-tune what time they display. If the start and end of DST changes, they still might not know.)
I think the effect of this news, regardless of the outcome, will be a slight acceleration of the idea that the correct time isn't what you have on your wrist -- that's just the presumed time (even though today's quartz clocks are frighteningly accurate). Rather, we're going to become more accustomed to clocks that set themselves, using data from centralized, government-certified time authorities. So, what time is it? It's what time The Man says it is.
