If your auction countdown is not behaving correctly, check to make sure your computer's time and time zone are set correctly, and the date and time are synchronized with an internet time server such as time.windows.com or time.gov.

Check your computer's time here:

If your computer's time is too fast or too slow, that can prevent you from bidding at the end of an auction. Either your computer will think the auction is over when it is not, preventing you from bidding, or else you will think you have more time left when the auction is about to end. Neither situation helps you. Set your computer's time to automatically synchronize to prevent this from happening.
