Examples

The following example demonstrates how to play the beep sound every second.

var tHours;
var tMinutes;
var tSeconds;
var oSelectedTimeZone = System.Time.currentTimeZone;

// --------------------------------------------------------------------
// Initialize the gadget.
// --------------------------------------------------------------------
function Init()
{    
    // Initialize the time display.
    DisplayTime();
    setInterval("DisplayTime()",1000);
}

// --------------------------------------------------------------------
// Display the system time based on selected time zone.
// --------------------------------------------------------------------
function DisplayTime()
{
    // 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;
        timeDisplay.innerHTML = tHours + tMinutes + tSeconds;
    }
    else
    {
        // Display something else.
    }
}
