1、定义一个CTime类对象 CTime time;
2、 得到当前时间 time = CTime::GetCurrentTime();
3、GetYear( ),GetMonth( ), GetDay( ), GetHour( ), GetMinute( ), GetSecond( ), GetDayOfWeek( ) 返回整型(int)对应项目
4、将当前时间格式化 CString date = time.Format("%Y-%m-%d %H:%M:%S %W-%A");
例子:
CTime ct = CTime::GetCurrentTime(); //获取当前时间 CString str = ct.Format("%Y-%m_%d %H-%M-%S");//格式化时间
结果:str="2006-04-23 15-21-30"

下面是另一个例子:
// Example for CTime::Format and CTime::FormatGmt CTime t( 1999, 3, 19, 22, 15, 0 ); // 10:15 PM March 19, 1999 CString s = t.Format( "%A, %B %d, %Y" ); ATLASSERT( s == "Friday, March 19, 1999" );
补充说明:“#”标志的含义
① %#a, %#A, %#b, %#B, %#p, %#X, %#z, %#Z, %#% ——“#” 被忽略
② %#c —— 把%c中的数字变成英文,再在前面加上星期, 如:“Tuesday, March 14, 1995, 12:41:29”.
③ %#x —— 把%x中的数字变成英文,再在前面加上星期,如:Tuesday, March 14, 1995
