RtlSecondsSince1970ToTime function (ntifs.h)

The RtlSecondsSince1970ToTime routine converts the elapsed time, in seconds, since the beginning of 1970 to an absolute system time value.

Syntax

NTSYSAPI VOID RtlSecondsSince1970ToTime(
  [in]  ULONG          ElapsedSeconds,
  [out] PLARGE_INTEGER Time
);

Parameters

[in] ElapsedSeconds

Number of seconds from midnight, December 31, 1969, to the current date and time.

[out] Time

Pointer to a caller-allocated variable that receives the corresponding current system time.

Return value

None

Remarks

The basis for system time is the start of 1601. The absolute system time is a LARGE_INTEGER value, accurate to 100-nanosecond resolution, assuming an accurate hardware clock. The value returned by RtlSecondsSince1970ToTime is truncated to one-millisecond resolution.

For more information about converting time values, see Data Conversions.
