Because when the cfml engine parses this line, it enters a static date
into the javascript, so it ends up being this:
function runMe() {
parent.showDate.document.write("blah blah");
}
So if you want the date to change, you have to either use a JavaScript
date object or you have to have it refresh the page...
Put this in a separate cfm template and load it into your frame
instead:
<body onload="window.setTimeout('location.reload()',2000);">
<cfoutput>#now()#</cfoutput>
<body>
Much simpler...
