I am curious, where did you find that third option? Is it u:zh.pad:MediaWiki:CountDown.js? If so, you should know that that particular JS solution malfunctions when you try to use more than one countdown.

I am not familiar with the JS and extension options, however, there is a simpler version you can implement using already enabled features. The downside is that it will be subject to page caching. The upside is that it will display the time according to the user's preferences. By default, this is UTC. The workaround for caching is also simple but not necessarily elegant.

Edit:

Sorry, as a countdown, a user's preference doesn't make a difference. However, it will use UTC so that the displayed countdown will be the same for all users. If I understand correctly, this is what you want.
