With bash builtins:

while IFS='T"' read -r a a b; do echo "$a"; done < filename

Output:

2012-05-04
2012-04-05
2012-03-05
2011-11-29

Through sed,

sed 's/"\|T.*//g' file

"matches double quotes \| or T.* starts from the first T match all the characters upto the last. Replacing the matched characters with an empty string will give you the desired output.

Example:

$ echo '"2012-05-04T10:16:04Z"' | sed 's/"\|T.*//g'
