What is a leap second

[Peter Ekberg]

Hello!

I compiled the following using msvc:

----------8<---------------------------
#include <stdio.h>
#include <windows.h>

typedef short CSHORT;
typedef struct {
	CSHORT Year;
	CSHORT Month;
	CSHORT Day;
	CSHORT Hour;
	CSHORT Minute;
	CSHORT Second;
	CSHORT Milliseconds;
	CSHORT Weekday;
} TIME_FIELDS, *PTIME_FIELDS;


typedef VOID (*RtlTimeToTimeFieldsT)
	(PLARGE_INTEGER Time, PTIME_FIELDS TimeFields);

int
main()
{
	LARGE_INTEGER RtlTime;
	TIME_FIELDS tf;
	HINSTANCE hLib;
	RtlTimeToTimeFieldsT RtlTimeToTimeFields;

	RtlTime.LowPart = 0x20de5700;
	RtlTime.HighPart = 0x1c27d90;

	hLib = LoadLibrary("ntdll");

	RtlTimeToTimeFields =
		(RtlTimeToTimeFieldsT)GetProcAddress					(hLib,
"RtlTimeToTimeFields");

	RtlTimeToTimeFields(&RtlTime, &tf);

	FreeLibrary(hLib);

	printf("%d %d %d %d %d %d\n",
		tf.Year, tf.Month, tf.Day,
		tf.Hour, tf.Minute, tf.Second);
	return 0;
}
----------8<---------------------------

with the following output on win2k.
9 0 10 0 9 10
