Why? The computer has many clocks in it and they are not all derived all from one master. So to answer we'd need to know which clock you care about. Obviously the clock to keep the current time of day can be sync'd from s master source, like GPS or an Internet NTP server. Maybe it's best you describe the big picture. What are you trying to do? But if you mean the audio interface. Then all you really need is a stable clock on that. There is an "elastic" buffer between the audio interface and the software so the computer can go off and do "whatever" for 1/10th of a second and the interface wil buffer the data, none gets lost as long as the buffer does not overflow. Modern CPUs do not run at a nice fixed rate. they are non-deterministic and might execute many instructions at once or even out of order. The newer Intel chips adjust their internal clock rates to control power use and core temperature. If you need to sync to the external world then software techniques are used -- Chris Albertson Redondo Beach, California _______________________________________________ time-nuts mailing list -- [email protected] To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there.
