假設有個time_t型的變數：time64

			char chTimeBuf[32] = {0};
			struct tm *ptr = localtime(&time64);
			strftime(chTimeBuf, 32, "%m-%d-%Y %H:%M:%S", ptr);

另：

time_t就是__int64或long

因為：

#ifndef _TIME32_T_DEFINED
typedef _W64 long __time32_t;   /* 32-bit time value */
#define _TIME32_T_DEFINED
#endif


#ifndef _TIME64_T_DEFINED
typedef __int64 __time64_t;     /* 64-bit time value */
#define _TIME64_T_DEFINED
#endif


#ifndef _TIME_T_DEFINED
#ifdef _USE_32BIT_TIME_T
typedef __time32_t time_t;      /* time value */
#else
typedef __time64_t time_t;      /* time value */
#endif
#define _TIME_T_DEFINED         /* avoid multiple def's of time_t */
#endif
