if the browser does scripting, and otherwise links to a time server:
document.write("<I>Right now:</I> " + new Date());
Check out the current time:
<A HREF="http://www.worldtimeserver.com">World Time Server</A>
which gives the following script and <NOSCRIPT> content. Remember that if your browser does scripting
then you won't see the contents of <NOSCRIPT>.
