I am creating a simple page with a big clock. I want the clock to change time a the correct moment, so I need to schedule the next display update to be the number of milliseconds remaining in the current minute. I was trying to use the Date class for this, but I am getting bad results.

Here's my Page ProntoScript.
var dsp = GUI.widget("TIME_DISPLAY");

UpdateDisplay();

function UpdateDisplay()
{
var d = new Date();
System.print(d.toString());
// set dsp.label
// calculate delay...
// scheduleAfter(delay, UpdateDisplay);
};

If run now, thee date that is displayed is:
Tue Feb 25 2031 03:02:11 GMT-0800
This is clearly wrong.

GUI.getDisplayTime() returns the correct time. Does this mean that the Date class is broken or unsupported or have I done something wrong.
