timethis

This is very small and handy C++ utility that will tells you about any command how long time it took to finish the execution or perform a simple DOS command along with user time and kernel time.

Example

c:\ExecTime.exe dir /s C:\

——————————–
Kernel Time     00:00:00:0000
User Time       00:00:00:0015
Creation Time   20:00:32:0734
Start Time      20:00:32:0749
End Time        20:00:32:0890
Elapsed Time    00:00:00:0141
——————————–

in above small example dir /s c:\ command took 141 mili seconds to execute.

Code Snippet

Here is small sample code snippet to print the time and this code is tested using Visual Studio 2012

struct myst:public SYSTEMTIME 
{ 
    myst& operator-(const myst& st) 
    { 
        myst t; 
        memset(&t,0,sizeof(t)); 
        int ntempHour = 0; 
        if(st.wDay != wDay) 
        { 
            ntempHour = (wDay - st.wDay) * 24; 
        } 
        unsigned long nSmall = st.wMilliseconds + st.wSecond*1000 + st.wMinute*60*1000 + st.wHour*60*60*1000; 
        unsigned long nBig = wMilliseconds + wSecond*1000 + wMinute*60*1000 + (ntempHour + wHour)*60*60*1000; 
        unsigned long  temp = nBig - nSmall; 
        while(temp) 
        { 
            if(temp > 999) 
            { 
                if(temp > 60*1000) 
                { 
                    if(temp > 60*60*1000) 
                    { 
                        t.wHour++; 
                        temp = temp - 60*60*1000; 
                    } 
                    else 
                    { 
                        t.wMinute++; 
                        temp = temp - 60*1000; 
                    } 
                } 
                else 
                { 
                    t.wSecond++; 
                    temp = temp - 1000; 
                } 
            } 
            else 
            { 
                t.wMilliseconds = temp; 
                temp = 0; 
            } 
        } 
        return t; 
    } 
}; 
myst StartTime;

---

void main() {
    GetSystemTime(&StartTime); 
    sprintf(csCurrentTime, "Start Time\t%02d:%02d:%02d:%04d", StartTime.wHour, StartTime.wMinute, StartTime.wSecond, StartTime.wMilliseconds ); 

    system(str2.c_str()); 

    printf("\n--------------------------------\n"); 
    PrintKernelUserTime(); 
    printf("\n--------------------------------\n");
}
