  set %startctime $ctime
}
;Stop the counter
on *:TEXT:!ooo*:#:{
  inc %OnAir. $+ $nick $duration($calc($ctime - %startctime))

This script is ment to total up the amount of time a user has been on air with our radio station. so they !ppp
when they go on air, then !ooo when they get off. That time then gets added to their total time to tell chan users
how long in total they have spent on air. Then !iii is to relay their total time to the chan

Any help is very much welcome.
