程序求助

#include <stdio.h>

int ChangeTime(char *sInTime, char *sOutTime)
{
char sYear[4],sMonth[2],sDay[2];
char sHour[2],sMin[2],sSec[2];

sYear[4]=0;
sMonth[2]=0;
sDay[2]=0;
sHour[2]=0;
sMin[2]=0;

strncpy(sYear,sInTime,4);
strncpy(sMonth,sInTime+4,2);
strncpy(sDay,sInTime+6,2);
strncpy(sHour,sInTime+8,2);
strncpy(sMin,sInTime+10,2);
strncpy(sSec,sInTime+12,2);

printf("%s\n",sYear);
printf("%s\n",sMonth);
printf("%s\n",sDay);
printf("%s\n",sHour);
printf("%s\n",sMin);
printf("%s\n",sSec);


printf("%s%s%s%s%s%s\n",sYear,sMonth,sDay,sHour,sMin,sSec);
printf("%s-%s-%s %s:%s:%s\n",sYear,sMonth,sDay,sHour,sMin,sSec);
sprintf(sOutTime,"%s-%s-%s %s:%s:%s",sYear,sMonth,sDay,sHour,sMin,sSec);

if(strlen(sOutTime)!= 20)
{
return -1;
}
return 0;
}

int main(int argc,char **argv){

char *sInTime,*sOutTime;


sInTime="20070301235959";

ChangeTime(sInTime,sOutTime);
printf("%s\n",sOutTime);
return 0;
}


程序运行到sprintf的时候core了，为什么
而且printf的时候的和gdb的时候也不一样，
哪位给指点一下
