multiple html pages with different display time in same iframe

i have 5 html pages and an iframe.

i need to display the html pages in an iframe with specific display time for each page. the delay should include the time for loading the i frame container. say first page have a display time of 10 sec 2nd page a display time of 20 sec ,3rd page a display time of 30 sec and so on.

how do i display all these pages bound to there display time. ?

i have tried many ways to add the load time my including iframe.load in the code but it causes some wiered recursions which alters the display time
