Milton,

I am working on an occultation project and thought that AstroIIDC and a Firewire camera would make a good solution given that your software can time code the frames. However, I wanted to get your view on two things:

1) Do you have any idea how accurate the clock is on your average Mac? Asked another way, if I have sync'd my Mac to a Internet time server, what is its fidelity to "true" time?

2) AstroIIDC appears to display time codes in standard pro video format - HH:MM:SS:Frame. While it is simple math to convert this "time" I was wondering if it were possible to have an option to display milliseconds (MS) rather than frame number.

Thanks,
