When a person joins a channel, they don't have a status yet, so they are always regular. Therefore you are doing your if checks in the wrong place, you should pass an alias to your timer, and check in that alias. If you want this only to work on regular users, as in not voiced/hoped/oped you can use: if ($nick isreg <channel>)
Additionally it would be a good idea to use the ! event prefix to prevent this script from triggering when you are the person joining.
On an ending note, I strongly advise you to specify an actual channel name in the on join event instead of just #, as that will trigger on any channel you are on, something the operators of channels where you are not staff will surely not appreciate.
