RtlSecondsSince1980ToTime function (ntifs.h)
The RtlSecondsSince1980ToTime routine converts the elapsed time, in seconds, since the beginning of 1980 to an absolute system time value.
Syntax
NTSYSAPI VOID RtlSecondsSince1980ToTime(
[in] ULONG ElapsedSeconds,
[out] PLARGE_INTEGER Time
);
Parameters
[in] ElapsedSeconds
Number of seconds from midnight, December 31, 1979, to the current date and time.
[out] Time
Pointer to a caller-allocated variable that receives the corresponding current system time.
Return value

Remarks
The absolute system time is a LARGE_INTEGER value, accurate to 100-nanosecond resolution, assuming an accurate hardware clock. The basis for system time is the start of 1601. The value returned by RtlSecondsSince1980ToTime is truncated to one-millisecond resolution.
