SYSTEMTIME (Windows Embedded CE 6.0)

1/6/2010

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.

wSecond: Specifies the current second.

wMilliseconds: Specifies the current millisecond.

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.

Requirements

Header	winbase.h
Windows Embedded CE	Windows CE 1.0 and later
