Note : The offset for timezones west of UTC is always negative, and for those east of UTC is always positive.
Test Data :
dt = new Date();
console.log(timezone_offset_in_seconds(dt));
19800

<!DOCTYPE html>
<html>
<head>
  <meta charset="utf-8">
  <title>JavaScript function to get timezone offset in seconds</title>
</head>
<body>

</body>
</html>

JavaScript Code:

function timezone_offset_in_seconds(dt) 
{ 
   return -dt.getTimezoneOffset() * 60;
}

dt = new Date(); 
console.log(timezone_offset_in_seconds(dt)); 

dt = new Date(1989, 10, 1); 
console.log(timezone_offset_in_seconds(dt));
