Changing / Adding Material over Real-World Time

Hey there guys/girls and unknowns,

I come in need of some help!

I want to add or change a Material or color over random times. Though I want to use Real-World time to set random intervals for it to change.

Note: Using Javascript, also here are the current variables I am using for time.

" var date = Date();

var day = date.Now.Day.ToString();

var month = date.Now.Month.ToString();

var year = date.Now.Year.ToString();

var hours = date.Now.Hour.ToString();

var minutes = date.Now.Minute.ToString();

var seconds = date.Now.Second.ToString(); "

Any possible help would be AWESOME!!!! And very grateful!

Regards,

Trent.
