在漂亮的格式显示在屏幕上的时间

Question

void clock(int hour, int minute){ 
wstringstream wss; 
time_t second; 
struct tm *current; 
current = localtime(&second); // get the running time which is in ms 
second = clock()/1000-extra; //now convert it to second, "extra" is 0 in the start 
char buffer[80]; 

if (second == 60){ 
    setminute(clock()/1000/60); 
    i=1; 
    extra=extra + 60*(i); 
    //when 60 passed, second will return to 0, i start at 0 in somewhere else; 
} 
else if (startminute == 60){ sethour(clock()/1000/60/60); setminute(0); } 

wss << starthour << " : "; 
wss << startminute << " : "; 
wss << second << " "; 
wss << "AM" << endl; 


textToGenerate.append(wss.str()); 
} 

这是我如何将程序运行时间转换为小时分秒格式。我在上午12:00设定时钟。它看起来像这样12 : 0 : 0 am在屏幕上

我想知道是否有反正我可以将格式更改为标准00:00:00 AM/PM

您可以使用R％的strftime。请看这里：http://www.cplusplus.com/reference/ctime/strftime/
