[ARC5] [Milsurplus] auction time linked to what timeing source?

[John Watkins]

Interesting discussion, but I just put in one bid usually and that's what I am willing to pay for the item. If someone else wants it more that I do, they bid more.  That way it really dosen't matter when the sniping starts if it does.  Nomex on.
