jquery plugin to show multiple elapsed time timers on a page?

I need to show on a page multiple -time zone independent- elapsed time timers. I'd like to have something similar to what is shown on the NASA mission pages, where they show the mission time (e.g. http://www.nasa.gov/mission_pages/shuttle/main/index.html).

I'd like to use a jquery plugin for that, so I'd like you to advice me on the most appropriate plugins for the job.

The perfect plugin would take an input independent of the client time,such as the elapsed 开发者_运维技巧seconds at the page download time, and start counting from that moment.

any help is greatly appreciated

jQuery Countdown might be able to serve that purpose.
