Does mac os x have some sort of a event sent out every 30 minutes?

Hell I'm trying to find out how to announce the time every 30

That's correct - you will need to figure out the next time you want
to make an announcement, given the current time, and calculate how
far in the future that is. Keep in mind that NSTimers don't
guarantee exact timing; they may fire slightly before or
significantly after the target date. (In other words, be careful
about handling "missed" announcements, especially in cases such as
the computer going to sleep or the user adjusting the time or time
zone.)
