I am working on an application that would most likely be on all the
time because it does lots of useful things, the time announcement
would just be an add on.

If you don't "need" this function "in" your app, or don't want to
have your app running all the time just to do the chime, you could
setup system preferences to let OSX do it for you. There may even be
a command line that can be executed under control of your app.

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.)
