This structure represents a date and time using individual members for the month, day, year, weekday, hour, minute, second, and millisecond.
Syntax
typedef struct _SYSTEMTIME {
WORD wYear;
WORD wMonth;
WORD wDayOfWeek;
WORD wDay;
WORD wHour;
WORD wMinute;
WORD wSecond;
WORD wMilliseconds;
} SYSTEMTIME;
Members
- wYear
Specifies the current year.
- wMonth
Specifies the current month; 1 indicates January, 2 February, 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.

Remarks
Millisecond granularity may not be supported by a hardware platform. The caller of this function should not rely on more than second granularity. It is not recommended that you add and subtract values from this structure to obtain relative times.
The following list shows tasks to perform instead:
- Convert the SYSTEMTIME structure to a FILETIME structure.
- Copy the resulting FILETIME structure to a ULARGE_INTEGER structure.
- Use usual 64-bit arithmetic on the ULARGE_INTEGER value.
