Usage: CLIENT <class> SET PING <value>

The time interval between pings sent to all clients that connect using the specified profile.

/as client WebMaster set ping 90

You probably shouldn't change the ping time without a good reason. The server sends pings to every client to make sure that they are still connected. Sometimes a user's client, computer, or network connection will crash without logging off of the chat network. This creates what is known as a ghost. The server will send pings and if it does not get a pong reply after a suitable wait, it will disconnect the client assuming it to be a ghost. Too high a ping time will flood the client by constantly asking it to reply and may lag users. Too low a ping time will leave ghosts on the network far longer.
