Modify this script for Time, not Date?

Question

I'm a complete newbie to scripting.  And I thought HTML was tough to pick up!
I have this script-- apparently the only one I could find that comes close to what I need.
// get new Date object
var d = new Date();
// format to mm/dd/yyyy
var sDate = util.printd("mm/dd/yyyy", d);
// insert date into form field
this.getField("todaysDate").value = sDate;
I need a script to perform this exact same operation but with the current system time (or MDT, that's fine).  I tried swapping out 'Date' for 'Time' but no go.  Anybody can help? 
Much appreciated...

Are you creating your form in Acrobat or LiveCycle Designer.
For Acrobat forms:
You can get a lot of different information from the date object by changing the format string for the 'util.printd' method. See the reference George Johnson links to for the format string values that can change the displayed value.
// get new Date object
var d = new Date();
// format to h:MM tt
var sDate = util.printd("h:MM tt", d);
// insert date into form field
this.getField("todaysDate").value = sDate;
h - hours without leading zero
MM - minutes with leading zero if necessary
tt - am or pm designator
For LiveCycle Designer you can select the 'Custom' form tab and then the 'Current Date' field. Now change the script to:
$.rawValue
= num2Time(time(), TimeFmt(1))
More information about the time format is the 'Scripting Reference' under LiveCycle Designer's 'Help' menu option.
