MIDITimeStamp ?

Hi !

A quick question about MIDI time-stamp:

<CoreMIDI/MIDIServices.h> says:
Since MIDI applications will tend to do a fair amount of
math with the times of events, it's more convenient to use a
UInt64 than an AbsoluteTime.

OK, but what is the format or unit (milliseconds?) of time-stamp in UInt64?
If I want to send a note-on message right now and note-off message after 1 second, what time-stamp values should I set for each MIDIPacket?

Thanks,
Joe.
