Astral Diamond Exchange to include a date stamp on Active Listings

I had 5 Active Listings all for the same amount but found something I wanted to purchase from the auction requiring to cancel 1 of my listings. However, I found I could not differentiate which listing was newest or which was oldest because they were all the same amount. I asked some friends to check this function but an anomaly was shared in which the order in which a new listing is posted wasn't consistent in being the topmost or bottommost. Including a date line of text in a listing, or a tooltip popup, would be useful because I wouldn't want to cancel my oldest offer and lose my place in the queue for Zen.
