A delay mechanism for iptables?

["Paul Hoffman" <phoffman@xxxxxxxxxx>]

Greetings. I want to use iptables packet manipulation to do something 
that I don't see in the man pages but would hope was there: delay the 
packets by a specified number of milliseconds. Is it in iptables but I 
am just missing it in the man pages? Or is there already an extension 
that I'm just not seeing in the default build on my Linux system?

(I know that this feature is supported in the dummynet package, but that 
package seems to be abandonware.)
