>>High-Resolution Timer routines. Usually used in combination woth QueryPerformanceFrecency to arrive at comparable time slices. Depending on your needs you can use either QueryPerformanceCounter as a raw value or measure time in small slices, build an index together with a date() or datetime() and a flag for "rollover happened today"... look it up in WinAPI

QueryPerformanceCounter/Frequency existed in W2K (would bet on it...) and AFAOR already NT. Should be well above anything needed for any disk based logging. Newer API's available via DotNet StopWatch ?
