myspace html coding

i have a myspace, and once in a while i like to change my background , songs, contact table ect ect... but i was wondering, is there an html code that has a time table with it so that the code inside will activate within certain hours of the day? for example, i could have a blue and black background , with a gold contact table and other stuff from 6pm-6am, then from 6:01am-5:59pm i have a black background with some symbols in it, and my contact table is brown this time ect ect...i dont have to do anything...just at those certain time tables those codes will kick in and change my myspace automatically. if so...please tell me the code, and if not, please tell me if this is actually possible on a site that i wanted to build myself and the site would change stuff everyday by itself
