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

the time interval set to NSDate interval from now to the time which
is like 7:30 or 8:00. but I'm not sure.
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.)
