Detailed Description

realtimeclock implementation for windows-systems

This class provides a RealTimeClock for windows-systems. Internally, it uses the QueryPerformanceCounter and the QueryPerformaceFrequency. It polls the current tick-counter, that counts from bootup. is supposed to be the most accurate time you can get on a windows-system.

double mitk::WindowsRealTimeClock::GetCurrentStamp ( )

virtual

returns the current time in milliseconds as a double

Uses the QueryPerformanceCounter to acquire an accurate time. (Ticks counted / Frequency) = time in ms

Implements mitk::RealTimeClock.

LARGE_INTEGER mitk::WindowsRealTimeClock::GetFrequency ( )

virtual

returns the QueryPerformanceFrequency

returns the QueryPerformanceFrequency, needed for acquiring the time from ticks
