Yes -- from the release notes:

    For HTML output a 'TextMate' javascript object is now exposed
    (property of window) with a system method that replicates the
    dashboard system method (in the 'widget' object). The method is
    documented here:
       http://developer.apple.com/documentation/AppleApplications/ 
Conceptual/Dashboard_Tutorial/Scripts/chapter_12_section_1.html.

    In addition it also has an “isBusy” property which you can set to
    true/false to get the progress indicator. Here's a somewhat small
    example of a clock (using “date”) which needs you to start it first
    (for a version that allows you to stop the clock as well, see:
    http://macromates.com:3000/read/chapter/2#page13):

    cat <<'EOF'
       <html><head><script>
          function start () {
             var cmd = "while true; do date; sleep 1; done";
             var process = TextMate.system(cmd, function (task) { });
             process.onreadoutput = function (str) {
                document.getElementById("date").innerText = str;
             };
          }
       </script></head>
       <body><span id="start">
       <a onClick="start()" href="#">Start</a></span>
       <div id="date"></div></body></html>
    EOF
