Actually, if I understand your post, you do need this.  The following script
checks the time once each minute.  Alternatively, you could check the time
at startup, do some math to calculate the offset to the next half hour, send
whatever message is needed when the interval is done, and then send all
future messages every 30 minutes.

on mouseUp
    set the twelveHourTime to false
end mouseUp

on runTimer
    set itemDel to ":"
    if item 1 of the time > 8 and item 1 of the time < 16 then
        if item 2 of the time is in "00,30" then
            ask "Please enter your data:"
            # callSpecialHandler it
        end if
    end if
    send "runTimer" to me in 60 seconds
end runTimer
