VC Get current Time

1. Using the CTime class

CString str;

Get system time

CTime TM;

Tm=ctime:: Getcurrenttime_r ();

Str=tm. Format ("Now time is%y year%m month%d day%x");

MessageBox (STR,NULL,MB_OK);

2: Get system time date (using Getlocaltime)

SYSTEMTIME St;

CString Strdate,strtime;

Getlocaltime_r (&ST);

Strdate.format ("%4d-%2d-%2d", st.wyear,st.wmonth,st.wday);

Strtime.format ("%2d:%2d:%2d", St.whour,st.wminute,st.wsecond);

3. Using GetTickCount

Get program Run time

Long t1= gettickcount_r ();//Get System Run time (MS) before program section starts

Long t1= GetTickCount ();

Sleep (500);

Long t2= Gettickcount_r ();();//Get System Run time (MS) after the end of the program segment

Long t2= GetTickCount ();

Str. Format ("Time:%dms", t2-t1);//The difference between the front and back is the program run time

AfxMessageBox (str);

4. Get the system run time

Long t= gettickcount_r ();

CString str,str1;

Str1. Format ("System is running%d", t/3600000);

STR=STR1;

t%=3600000;

Str1. Format ("%d", t/60000);

STR+=STR1;

t%=60000;

Str1. Format ("%d Seconds", t/1000);

STR+=STR1;

AfxMessageBox (str);

5. Calculate the number of seconds from January 1, 1970 0:0 0 seconds to that point in time

#include <iostream>

#include <ctime>

using namespace Std;

int main () {

time_t Now_time;

Now_time = time (NULL);

cout<<now_time;

return 0;

}

6. Use the system function to change the computer's time setting

#include <stdlib.h>

#include <iostream>

using namespace Std;

void Main () {

System ("Time");

}
