Used to calculate Client's ping. The received UINT32 should be sent directly back to Battle.net.
The ping displayed when in chat can be artificially inflated by delaying before sending this packet, or deflated by responding before requested. Ping can be set to -1 (Strictly speaking, 0xFFFFFFFF, since ping is unsigned) by not responding to this packet at all.
The received UINT32 is not what determines your ping, but it is actually a cookie for the Battle.net server. You should never change the UINT32.
