You have _two_ concerns here. First is what to do when you save
"meetings.org", second is what to do every half hour. Your code
handles both of them, essentially correctly, but in the wrong place.

This means the code will only execute if the current buffer is
"meetings.org" when it executes. That _is_ what you want when you save
meetings.org, but it _is not_ what you want when the timer executes.

Break out the body of the `when' form into its own function, and call
that function from the timer, instead of `z/save-meeting-to-ics'.

For this, you need to add `z/save-meeting-to-ics' to the Emacs global
variable `after-save-hook' using function `add-hook'.

You mean 1800 seconds, I think.
