textures change with a day and night script

I am building a home and he two textures one is a day textures that does not have night light reflections and another texture that does. What I want to know is there any way I can have 2 textures that will change with night to day and day to night. I know how to make textures that move back and forth to show action. What I want is to have it change with the sim day and night reflections I have in these two textures. Thank you if you can help.

There are examples of detecting day and night time here.

You will need to modify them to set textures in whichever manner you choose.
