 SYSTEMTIME

The SYSTEMTIME structure represents a date and time using individual members for the month, day, year, weekday, hour, minute, second, and millisecond.

typedef struct _SYSTEMTIME { 
    WORD wYear; 
    WORD wMonth; 
    WORD wDayOfWeek; 
    WORD wDay; 
    WORD wHour; 
    WORD wMinute; 
    WORD wSecond; 
    WORD wMilliseconds; 
} SYSTEMTIME, *PSYSTEMTIME; 

Members

wYear
Specifies the current year.
wMonth
Specifies the current month; January = 1, February = 2, and so on.
wDayOfWeek
Specifies the current day of the week; Sunday = 0, Monday = 1, and so on.
wDay
Specifies the current day of the month.
wHour
Specifies the current hour.
wMinute
Specifies the current minute.
wSecond

wMilliseconds

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.
