I didnt ask what the value was, I asked what is needed to be done with it. When you send a ping to someone it sends that number, when their client sends the ping reply, what does it do with that number so I can get the correct lag.
We don't just write the scripts, we put them to the test! (ScriptBusters)
Hammer receives it and subtracts the numeric value after the PING from his current $ctime to retrieve the difference between the ctime he sent the ping and when he got the response back.
on *:CTCPREPLY:PING*: echo $color(ctcp) -ati2 * Ping response from $nick is $duration($calc($ctime - $2)) $+ .
