FILETIME

The FILETIME structure is a 64-bit value representing the number of 100-nanosecond intervals since January 1, 1601.

typedef struct _FILETIME { // ft 
    DWORD dwLowDateTime; 
    DWORD dwHighDateTime; 
} FILETIME; 
 

Members

dwLowDateTime

Specifies the low-order 32 bits of the file time.

dwHighDateTime

Specifies the high-order 32 bits of the file time.

Remarks

It is not recommended that you add and subtract values from the FILETIME structure to obtain relative times. Instead, you should

• Copy the resulting FILETIME structure to a LARGE_INTEGER structure.
• Use normal 64-bit arithmetic on the LARGE_INTEGER value.
