[XP] REAL TIME Day/Night system

I have looked all over for something like this, but nothing came up. I even looked here and even on those bigger RPGM forums.

So basically what I need this script to do is

-Take the time of the computer
-If the time is from 5AM to 8AM, and 5:30PM to 7:30PM, tint the screen orange (Like sunset/rise)
-if the time is from 8AM-5:30PM, leave the screen alone (use default tone)
-if the time is from 7:30PM to 5AM, tint the screen purple/blue/just dark (most realistic darkness.

Sorry for the trouble, I'm still at an early stage at learning ruby and I can't find this anywhere else. Thanks.

Have you seen this?

Side note: sometimes you have to dig through pages of forum posts, as many scripts arent listed neatly in one nice list on each site.

I did see that, but I don't want the weather, and I don't think it says that it takes the time of the computer anywhere on there.
