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.
