Re: 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
