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

If your computer's time is ahead by one minute your auction countdown will be off by one minute as well. When your countdown reaches zero there will still be one minute left in the auction for others to bid, but you will not be able to bid since your countdown has already indicated that the auction is over even if your clock appears to start counting down from 59 seconds again.
If your computer's clock is actually synchronized then this problem does not occur.
