- The additional 10 millseconds in this example is due primarily to the quantization error in the timing (this setup used a 10 millisecond periodic system timer). - Other sources of error could include the additional overhead of the time command execution itself which is included in the total. + The additional 10 millseconds in this example is due to the way that the sleep command works: It always waits one system clock tick longer than requested and this test setup used a 10 millisecond periodic system + timer. + Sources of error could include the additional overhead of the time command execution itself which is included in the total and various quantization errors.
