Jeroen -
    read.table is not converting anything.  You're confusing
the output you see at yahoo with the contents of the csv file.

> two[1:3]
[1] "Date,Open,High,Low,Close,Volume,Adj Close" 
[2] "2010-04-15,592.17,597.84,588.29,595.30,6716700,595.30"
[3] "2010-04-14,590.06,592.34,584.01,589.00,3402700,589.00"

This shows that the dates have been faithfully copied from the 
csv file with no conversion.
