4. You must specify an exact end time, of which time zone, and the date. NO "ends *hours after last bid" allowed. AT YOUR LEISURE, you may also allow for provisions of anti-sniping, so that a bid placed within the last 5 minutes of the auction would extend the auction by an additional 5 minutes to the clock. The standard to this rule, if its not exactly specified by the thread starter is this - 4 minutes remaining, bid placed, 5 minutes get added, so clock gives 9 total minutes till end of auction. If 1 minute or less is remaining, 5 minutes get added, so the clock gives 6 total minutes before auction closes. This is the standard to be used whereby anti-snipe is in place (and ONLY if anti-snipe is in place as would be stated by the auction holder). If anti-snipe is NOT clearly specified, it is not in effect. Anti-snipe is a new procedure in effect as of April 10, 2008 (4/10/2008).
