Do NOT waste your time with /timers. Use event-based coding methods instead.

This is what you actually want.
Code:
; End of /NAMES ($2 == channel)
RAW 366:*: {
  if ($2 == #MyChannel) && ($me isop $2) {
    do stuff.
  }
} ; by Raccoon 2017

Well. At least I won lunch.
Good philosophy, see good in bad, I like!
