COleDateTime 을 이용하여 계산하기

1. 두 COleDateTime 객체간의 차이를 구할 때는

COleDateTime ATime(2007, 4, 26, 17, 20, 30);
COleDateTime BTime(2007, 4, 26, 18, 20, 50);

COleDateTimeSpan C = BTime - ATime;

C.GetTotalDays() - 차이나는 총 날짜
C.GetTotalHours() - 차이나는 총 시간
C.GetTotalMinutes() - 차이나는 총 분
C.GetTotalSeconds() - 차이나는 총 초

2. CString 으로 바꾸고 싶다면.. 멤버 함수 Format 을 사용하면 된다.

COleDateTime nowTime(COleDateTime::GetCurrentTime());
OutputDebugString(nowTime.Format(_T("%H:%M:%S\n")));

Format 에 들어가는 것은

%a     Abbreviated weekday name

%A     Full weekday name

%b     Abbreviated month name

%B     Full month name

%c     Date and time representation appropriate for locale

%d     Day of month as decimal number (01 – 31)

%H     Hour in 24-hour format (00 – 23)

%I      Hour in 12-hour format (01 – 12)

%j      Day of year as decimal number (001 – 366)

%m    Month as decimal number (01 – 12)

%M   Minute as decimal number (00 – 59)

%p    Current locale's A.M./P.M. indicator for 12-hour clock

%S    Second as decimal number (00 – 59)

%U    Week of year as decimal number, with Sunday as first day of week (00 – 53)

%w   Weekday as decimal number (0 – 6; Sunday is 0)

%W   Week of year as decimal number, with Monday as first day of week (00 – 53)

%x    Date representation for current locale

%X    Time representation for current locale

%y    Year without century, as decimal number (00 – 99)

%Y   Year with century, as decimal number

%z, %Z  Either the time-zone name or time zone abbreviation, depending on registry settings; no characters if time zone is unknown

%%   Percent sign

3. 지정된 시간에서 '분'을 더한 시간 계산

void UpdateTime( SYSTEMTIME& stPatchTime, INT32 wMinute )

{

COleDateTime PatchTime( stPatchTime.wYear, stPatchTime.wMonth, stPatchTime.wDay, stPatchTime.wHour, stPatchTime.wMinute, stPatchTime.wSecond );

 

COleDateTimeSpan SpendTime;

SpendTime.SetDateTimeSpan( 0, 0, wMinute, 0 );

PatchTime += SpendTime;

          

stPatchTime.wYear = PatchTime.GetYear();

stPatchTime.wMonth = PatchTime.GetMonth();

stPatchTime.wDay = PatchTime.GetDay();

stPatchTime.wHour = PatchTime.GetHour();

stPatchTime.wMinute = PatchTime.GetMinute();

}
