Fix Countdown Timer for Local Time in Live Streaming Site

I have added the Event item header to a site that is for live streams so I wanted to use the countdown timer to have above the video. But the issue I'm having is that the count down timer is not matching the Local time - GTM+10 so it is showing in a negative time (-1 day) for the day of the live stream. I have the site settings time set at GTM+10 but I have now way to allocate the time zone to the timer. I'm not sure where its getting its default time from, but it's not matching to the local time. The timer uses a js, and was hoping that someone had come across this and has been able to find some additional js to get the site set local time or add it in to the js.
