Apple clock / calendar / iPod sync problem

I live in Argentina and this year the government has decided not to use daylight saving so last weekend there was no change in time as was expected in the digital world.

As a result I have had to switch off the automatic clock (which jumped and hour ahead) and reset it manually.

The problem I am having is with my iPod 60Gb (pre-Classic - G5 I think). With the Time Zone set to Buenos Aires, Daylight Saving off and time set correctly everything is fine. But when I connect to my MacBook it changes the setting to Daylight Saving on and all my appointments (on the iPod only) one hour later!

Any advice?

Ggggrrrrrrrr
