windows -> preferences -> c/c++ -> code style -> code template
Edit File Comment in the comment template on the right and change it to the mode you want. for example:
/*********************************************
* ${file_name}
* Author: ${user}
* Created on: ${date}
********************************************/
Then find the eclipse.ini file in the eclipse installation directory and add: -Duser.language=en_US
Restart eclipse. Now the date produced by the ${date} variable is all in English.
