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.

If your computer's time is ahead or behind by fifteen seconds, this can cause problems bidding in the last fifteen seconds of an auction, as your countdown will not be correct. Synchronizing your clock should do away with this problem.
