Need Flash work, java script programming-- not exactly sure! Details inside!

Hey there everyone! I am not quite sure what it is I need! HA! Remember the show JAG? ([login to view URL] ) If you go to the URL above, within the first 4 seconds, you will see writing in that "commodore 64 green" develop across the screen "0145 ZULU".. and it continues. I need a black background with text that does the same. However, on the time (the 0145), I need it to be dynamic to each user. So, when a user comes to my website, their time will automatically be turned into ZULU time (GMT) and display across the screen, just like above. And the I'll have some text following (I haven't decided what I want it to say.) I know for certain, the time. And then it will be a short blurb. How is this done? Is it flash/javascript? Or can it even be done? What would your turn around time be? Thanks so much! I can't wait to hear from y'all!
