... and there is no answer.
My vote - ditch the daylight savings time, and ditch the time zones. Lets make some timezone global, and everyone uses that timezone. I wrote a comment in Treehugger (http://www.treehugger.com/health/forget-just-getting-rid-daylight-saving-time-lets-get-rid-time-zones-and-go-local.html) 8 months ago, on the previous clock move discussion, and most of it I'll copy here:
For the last 5000 years humans are thought that sun is high in the sky at midday. Only way to detect time were sundials (even if old Romans had hourglass or something like that, they must be watched over constantly so they were not an option for reliable timekeeping). In the last 500 years we have mechanical clocks and we defined parts of day more precisely - hours, minutes, seconds. Timezones are here only in the last 150 years, and daylight savings time in the last 70 (and most people despise daylight savings time as it's not natural).
And daylight savings time is the argument against keeping timezones. Humans chose time measurement according to Earth rotation around the sun. On spring and autumn solstice (equinox) there is 12 hours of light and 12 hours on night. Why didn't they chose 12 as a number of hours, and not 10? Or 8? But as it is, we have hours, minutes and seconds, and our whole physics and other sciences revolve around those units.
So what is time? Or local time? It's just a number which we, humans, decided on. There is another example of time we humans decided: Unix timestamp or epoch. Used in computers it measures number of seconds since January 1st 1970 at 00:00:00 UTC.
What does daylight savings time has with it that's an argument for making time global? The answer: why are we moving clocks back and forth, to accommodate a system which should help us, to natural change of how long does a day and night last. Because our laws, work contracts and everything similar (again, human tools which could be changed) state the beginning and ending of an activity. And instead of changing those, we chose to move the clock?!?!?
I agree, in global time nobody would like to go to bed at 14:00, and go to work at 23:00, because everybody thinks that 14:00 is in the afternoon and 23:00 is in the middle of the night. But for some, if we used a global time system, that 14:00 would be middle of the night, and 23:00 would be the morning. 14 is just a number, a tool. For those whose time would become global, the number would stay the same, for others it would change. But everything would change - Google calendar could not expect that 13 o'clock is time for lunch because in your region lunch is now at 4:00 (and in reality it's somewhere around noon)
And there is another reason to change to global time real soon - space travel. When first colonist go to Moon, Mars and other planets in our solar system, how should they measure time. Locally? To the clock of some nation (first to colonize)? Should they use an Earth second or a Moon or Mars second? Should they still use a second, but set up a different number of seconds for a minute or an hours, and then use a standard 24 hours/day calculation?
We need a global system of time NOW. Used reasonably, with changes in work laws, school calendars etc. But we need IT. Is it Swatch Internet Time, is it UTC time or anything else.
Forces of habits are tough to beat. Only loss in global time is that 12 o'clock is not high noon, with a sun high in the sky. Oh wait, even now that's not the case if you're in a big timezone!
So forget the dayligh savings time, forget the timezones, forget that the time on your watch has a special meaning. You'll wake up in the morning, you'll go to sleep in the evening.
