Time coding

I am working in Flash5. My problem is that I want my animation to run after every 5 minutes.
I mean that when I run my fla file, it should load my animation when 5 minutes has passed, then there
should be a break and screen should become blank , and then again after 5 minutes it should appear
and run.
I want this process to keep on happening.

if this is not possible ,can that be done through HTML code as i want to put it on my web page,what would be the html coding in that case.
An IMPORTANT point is that, I want the coding to be in FLASH5,if done in flash.
If done in the form of fla file,or html code will be very appreciated.
Thank you,
