{
// Retrieve the local time.
var sTimeInfo = System.Time.getLocalTime(oSelectedTimeZone);
if (sTimeInfo != "")
{
System.Sound.beep();
var dDateInfo = new Date(Date.parse(sTimeInfo));
tHours = dDateInfo.getHours();
tMinutes = dDateInfo.getMinutes();
tMinutes = ((tMinutes < 10) ? ":0" : ":") + tMinutes
tSeconds = dDateInfo.getSeconds();
tSeconds = ((tSeconds < 10) ? ":0" : ":") + tSeconds;
