- Calculate an event's duration in timer ticks.

- calculate the duration of the event in timer ticks. Information for
- the current measurement is pointed to by the parameter.
-
- If the measurement's start time is 1, it indicates that the developer
- is indicating that the measurement began at the release of reset.
- The start time is adjusted to the timer's starting count before performing
- the elapsed time calculation.
-
- The calculated duration, in ticks, is the absolute difference between
- the measurement's ending and starting counts.

- @param Measurement Pointer to a MEASUREMENT_RECORD structure containing
- data for the current measurement.

- @return The 64-bit duration of the event.
