| Function | Library | Purpose |
|----------|---------|---------|
| Sleep | user32.dll | Thread sleep |
| SetTimer | user32.dll | Creates message-based timers |
| timeGetTime | winmm.dll | Retrieves system uptime in milliseconds |
| GetTickCount | kernel32.dll | Retrieves system uptime in milliseconds |
| GetTickCount64 | kernel32.dll | Retrieves system uptime in milliseconds (64-bit) |
| QueryPerformanceCounter | kernel32.dll | High-resolution performance counter |
| GetSystemTimeAsFileTime | kernel32.dll | Retrieves system time |
| GetSystemTimePreciseAsFileTime | kernel32.dll | Retrieves high-precision system time |
| SetWaitableTimer | kernel32.dll | Sets a waitable timer |
| SetWaitableTimerEx | kernel32.dll | Sets a waitable timer (extended) |
