Set Pacific Time Zone. Never been able to "properly" do it.
 

Simply put:

Everytime I installed Linux I could never get the Time Zone to set right. I always just "hard-switched" the time to be accurate.

However this will no longer do. Whenever I collaborate in ODC (Excel etc.) I get the dates looking like DD/MM/YY whereas I am accustomed to MM/DD/YY. Now I now I can also set that to look how I want but once my co-workers look at it in windows they are like "WTF, the dates are messed up!".

I have only one clue: Whenever I set my time I set it to the place closest to me (Located Seattle,WA,USA area) I always get Vancouver, BC, Canada.

So has anyone had a problem like this or is it just my stupidity (most likely)? A solution or some tips? What timezone should I pick and etc.??

You would think that I could make sense of it....but who knows.

I thought now would be the best time since I am doing a system re-install.

Date format and time zone are different things and set separately. It sounds like you set the time zone OK but you didn't mention setting the format. Applications, certainly Nautilus, allow you to set date format. DD/MM/YY is common in the rest of the world.
