javascript: change the countdown timer from the local time to the specific time zone

The code we are currently showing is:

This is showing a countdown timer. But it is based on a specific time based on the location of the users.

Instead, we want to show a difficult date at 3 pm Pacific Time (PST). So that no matter where you are in the world, the countdown shows the same amount.

The js code is the following.

$ (function ()

{
var countDownClock =
{
iniClock: function (date)
{
// calculating days, hours, minutes and seconds to date.
date = date.split (& # 39;: & # 39;);
