Getting back to 'normal time'?

In today's papers:
San Luis province is rebelling against the government's time change and will turn its clocks back one hour on Monday at 0:00 hrs. Ha! That means Argentina will have two time zones next week to add to the confusion.

So, I'm not the only one frustrated by the time change that has the whole country just 2 hours off Greenwich Mean Time (and 3 long hours off NYC time). Are we saving energy? In some spots in Argentina, the hot summer sun may not set until after 10 PM. While that may save light bulbs from being turned on, it puts more of a burden on energy-guzzling air conditioners during peak evening hours.

Peddling back for a moment, it seemed crazy to me that daylight savings time was decreed on Dec. 26 & put into effect just 4 days later, on Dec. 30. Computers are still confused by the sudden move. As a temporary patch, Windows users are advised to switch their time-setting from "Buenos Aires, Georgetown" to "Mid-Atlantic." Any wonder I feel at sea?
