Timestamp

The timestamp function of the Keithley 6430 is based on an internal oscillator with a frequency of 8.192kHz. Ticks occur every 8.192kHz/8 or 1024 a second, which means a system tick occurs every 0.9765625. The reported timestamp value is thus off by 24 ms every second. To obtain a more accurate timestamp value, we must multiple the timestamp by a factor of 0.9765625. Hmmm....
