"Total Time spent on board" Query?

[Sergg]

I'm new to modding and editing vb files of any sort. I have installed quite a few and had no problems. However, I ran into this mod/edit "Total Time spend on Board". The problem is that I have no clue how,where, or what this query is, how I actually carry out this specific task.

This is a quote from the install guide text

ALTER TABLE `user` ADD `timeonboard` INT( 10 ) NOT NULL AFTER `lastactivity` ;

Hopefully someone here will be able to help me out. Handling the rest of the install is easy enough. I'd hate to think that the answer is stairing me right in the face.
