Adding a Numerical function?

After working ALOT with numbers in scripts (naturally...) I'm getting tired of having to create my silly boolean for determining numbers as "Odd" or "Even" everytime I make a Window Selectable that I want to use an alternating placement structure.

E.G.
NORMAL:
1
2
3
4

ALTERNATING:
1 2
3 4

Anyhow, I find myself repeatedly using this method for menus and having to make a boolean for it. I already realize I can just add the boolean structure to Window_Selectable itself as a new argument for the class being "Alternating" or "Normal" sorting method. (I have done so before.)
However, I also find myself needing this in other situations besides sorting methods...And so, I am wondering:

How do I go about adding a "Odd" or "Even" determinating function to the Numerical class? Or in that case, adding a function to any pre-existent class in RMXP?

Code: [Select]

if (value % 2) == 0
   blah blah blah even
else
   blah blah blah odd
end

Hahaha well, I suppose I am still new to the shortcuts and ways of scripting. All the methods and such aren't quite in my brain yet. Well, thanks .

Also, I had a veyr pressing question...If I need to make another topic for it don't hesitate to direct me to do so >.<. Anyhow, I want a Game Clock for my game that is real-time. i.e. If you're playing at 12:30 A.M. It's dark out, and so on. Of course, the game can't process when it isnt running, so this is impossible unless I sumhow access an outside program, like Window's own clock and calendar.

So, how do I access computer data such as Window's clock and use it as a variable or set of variables?

I think you'll find an answer on google, I'm not sure.
I'm 99.5% sure someone did that already.
