|---------------|---------|-------------|
| Sleep | user32.dll | Thread sleep |
| SetTimer | user32.dll | Create message-based timer |
| timeGetTime | winmm.dll | Get milliseconds elapsed since system startup |
| GetTickCount | kernel32.dll | Get milliseconds elapsed since system startup |
| GetTickCount64 | kernel32.dll | Get milliseconds elapsed since system startup (64-bit) |
| QueryPerformanceCounter | kernel32.dll | High precision performance counter |
| GetSystemTimeAsFileTime | kernel32.dll | Get system time |
| GetSystemTimePreciseAsFileTime | kernel32.dll | Get high precision system time |
