GetSystemTimePreciseAsFileTime (defined in sysinfoapi.h ) retrieves the current system date and time in a single FILETIME structure (a 64-bit value counting 100-nanosecond intervals since January 1, 1601 UTC). The “Precise” in its name is the kicker: it returns the most accurate system time-of-day available, often incorporating the high-resolution performance counter to interpolate between system clock ticks. getsystemtimepreciseasfiletime windows 7 patched
// Start from the initial system time and add offset preciseTime = ((ULONGLONG)initialTime.dwHighDateTime << 32) + initialTime.dwLowDateTime; preciseTime += elapsed; And if your scenario allows for it, consider
// Get current performance counter QueryPerformanceCounter(¤tCounter); avoid kernel patches unless absolutely necessary
Introduction: The Quest for Accurate Time In the world of software development, timing is everything. From high-frequency trading algorithms and database transaction logging to performance profiling and multimedia synchronization, the ability to query the system time with high precision is non-negotiable.
However, with caution as your watchword. Test extensively in a sandbox, avoid kernel patches unless absolutely necessary, and always have a rollback plan. And if your scenario allows for it, consider that the best patch may simply be moving to a modern OS where this precision is native, secure, and supported.
