<p>
The addition 100 microseconds in this example is the additional overhead of the time command execution itself which is included in the total.
Timing quantization errors could also result in small errors in the measurement.
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.
