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

Remarks

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

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