Description
This sample exclusively deals with time measurement such as
- Querying the task cycle time in nanoseconds
- Querying the task priority
- Querying the time when the task cycle starts at intervals of 100 nanoseconds since January 1, 1601 (UTC)
- Querying the distributed clock time when the task cycle starts in nanoseconds since January 1, 2000
- Querying the time when the method is called at intervals of 100 nanoseconds since January 1, 1601 (UTC)
