Stop playing games with time. Instead of year-long daylight saving time, I'd rather we stick with standard time all year long.
Anyway, what the article is really saying is that people should work 8-4 instead of 9-5, because then they commute home before it gets dark and are at less risk for muggings, robberies, and rapes. Which is true, but it's kinda silly that to get there we should just change the meaning of time rather than the hours we work. Then again, maybe that is the most effective way to effect society-wide change.
We already have Standard time. Daylight saving time is Standard time +1 hour.
My idea would be to stay on this, all year long, without pushing the clocks ahead/back twice a year.
Remembering which country is where is standard in school, roughly estimating timezones from that is easy (US varies from -8 to -4, most of europe is 0 or +1 or +2, as is most of Africa, Russia is +3, middle east is around +3 and +4, china is +8, just like singapore and japan; australia, new zealand are between +10 and +12; I have no idea what the actual data is, just saying what I remember based on knowing the world map)
As everyone knows GMT, and everyone knows the world map, the issue is solved.
Google calendar is even smart enough to "translate" an event to your timezone. If I get an email with an event in a different timezone and put it on your Google Calendar it actually goes on your calendar in your local time zone. This screwed me up once when I moved to the other side of the world and forgot to update my timezone in Google.
