Here's source for a .mex file that does what you want. It looks like I can't post files, so if you can't compile it and need the .mex file itself let me know and I'll be glad to pass it to you (somehow).
/*=================================================================
*
* FileTimeToSystemTime.c
* returns SYSTEMTIME for FILETIME
*
* The calling syntax is:
*
* [st] = FileTimeToSystemTime(pFt)
*
*
*=================================================================*/

#include <math.h>
#include "mex.h"
#include "matrix.h"
#include <windows.h>

/* Input Arguments */

#define pmxFt prhs[0]


/* Output Arguments */

#define pmxST plhs[0]



static void mxFileTimeToSystemTime(SYSTEMTIME * pSt, FILETIME * pFt)
{FileTimeToSystemTime(pFt, pSt);
}

void mexFunction( int nlhs, mxArray *plhs[], int nrhs, const mxArray *prhs[] )
{const mwSize pmxOutputDims[] = {1,8};
SYSTEMTIME * pSt;
unsigned int * pFt;
// mwOutputSize m, n;

/* Check for proper number of arguments */

if (nrhs != 1)
mexErrMsgTxt("one input argument - ptr to int[2] filetime - required.");

if (nlhs > 1)
mexErrMsgTxt("Too many output arguments.");

/* Check the dimensions of Y. Y can be 4 X 1 or 1 X 4.

m = mxGetM(Y_IN);
n = mxGetN(Y_IN);
if (!mxIsDouble(Y_IN) || mxIsComplex(Y_IN) ||
(MAX(m,n) != 4) || (MIN(m,n) != 1)) {
mexErrMsgTxt("FileTimeToSystemTime: Output must be tbd");
}
*/
/* Create a matrix for the return argument */
pmxST = mxCreateNumericArray(2, pmxOutputDims, mxUINT16_CLASS, mxREAL);

/* Assign pointers to the various parameters */
pSt = mxGetPr(pmxST);

pFt = mxGetPr(pmxFt);

/* Do the actual computations in a subroutine */
mxFileTimeToSystemTime(pSt, pFt);
return;

}
