I am currently working on a Blog that is covering events of World War one in "real time". To accomplish this i would to set the entry dates to 1914. Doing this in the Wordpress admin interface obviously doesn't do the trick. 
So now i'm wondering how to accomplish this. 
Option one: Adjust the template, but then i would have to actually modify a lot of code and have the problem all over again as soon as i change templates.
option two: modify wordpress' get\_the\_date function. 
Other options?
