>>I'm building a timeclock buzzer application. At certain times during the day buzzer.wav plays. So I need to figure out how to fire off these events. The times I want buzzer.wav to play is something like...

>>05:59
>>06:00
>>11:29
>>11:30
>>14:29
>>14:30

>>I can use a timer and compare the system time but I need the timer interval to be less than 1 minute (as you can see above) and that could cause the buzzer to play multiple times within that time slot. Any ideas?

This sound inaccurate. Seems like it could wander using this method. That's why I figured if every 10 seconds I could look and see if my machine time (atomic time) was 05:59 I would play the wav. Your method leaves me at the mercy of the internal clock tick correct?
