Detailed Description

System time plus associated cycles counter values.

The structure holds a system timestamp in a format depending on the target OS plus two cycles counter values which can be taken before and after reading the system time. These cycles values can be used to determine the execution time required to read the system time.

Limitations of the operating system need to be taken into account, e.g. the Windows system time may increase once every ~16 ms or ~1 ms only, depending on the Windows version.
