jQuery Countdown and User's Local Time

jQuery Countdown and User's Local Time

I wish to use a jQuery countdown timer; but want the time-keeping to be in sync with the UTC time; and not the user's system time. I'm using  http://hilios.github.io/jQuery.countdown/ and got the countdown to work as expected; but with one big problem: The countdown takes into account user's local time as current time. I'd however want the plugin to make use of UTC time ( seconds ) for the timer to be precise. 

I'm looking for a jQuery countdown snippet that'd achieve this. Perhaps, I need to modify the code available here:  https://stackoverflow.com/questions/20618355/the-simplest-possible-javascript-countdown-timer , but I'm not sure how to do it. 

Would appreciate if you could help. 

Thanks a lot for your time. I really appreciate it.
