+	When the equipment we hold for a guild member reached us.

+	It has always been written down - the transfer below sets it - but nothing ever read it, so
+	a panel filled from a copy received weeks ago looked exactly like one filled a second ago.
+	That matters here more than anywhere else in the addon: this data does not refresh on its
+	own. It only arrives when the member, or their main, is online and answers, so a stale copy
+	can stay stale for months.
+
+	Our own characters are answered from our own tables, which are written as we play, so there
+	is no timestamp to give and none is wanted.
