typedef struct _SYSTEMTIME {
  WORD wYear;

  WORD wDay;
  WORD wHour;
  WORD wMinute;
  WORD wSecond;
  WORD wMilliseconds;
} SYSTEMTIME;

Remarks

It is not recommended that you add or substract values from this structure to obtain relative times. Instead, you should do the following:

Convert the SYSTEMTIME structure to a FILETIME structure using the SystemTimeToFileTime function.
Copy the resulting FILETIME structure to a ULARGE_INTEGER structure.
Use standard 64-bit arithmetic on the ULARGE_INTEGER
value or cast a variable of FILETIME type to the __int64 type:
```
FILETIME WriteTime1, WriteTime2;

if(*(__int64*) & WriteTime1 == *(__int64*) & WriteTime2)
 ...
```
