I have an auction use case where, if a bid is posted within 30 minutes of the auction close, 30 minutes is added to the clock. All other auction details are refreshed without a page refresh using AJAX. I have parsed through the documentation and the JavaScript Timer source but was unable to find a way of refreshing the timer. If I missed something and there is a simple way of refreshing the timer value, my apologies. If I did not, this might be a useful addition to the module.
