Two ways to realize time format printing

utilize Time function to realize time format printing

#include <time.h>
#include <ctype.h>

time_t rawtime;
struct tm timeinfo;
TCHAR szTime[100];

time ( &rawtime );
localtime_s ( &timeinfo, &rawtime );

_tcsftime( szTime,ARRAYSIZE(szTime), _T("%a %Y-%m-%d %X"), &timeinfo);

Time format printing is realized by using traditional string printing function

#include <time.h>
#include <ctype.h>

time_t rawtime;
struct tm timeinfo;
TCHAR szTime[100];

time ( &rawtime );
localtime_s ( &timeinfo, &rawtime );

sprintf_s(szTime,ARRAYSIZE(szTime), 
        "%4d-%02d-%02d  %02d:%02d:%02d",
        1900+timeinfo.tm_year,
        1+timeinfo.tm_mon,
        timeinfo.tm_mday,
        timeinfo.tm_hour,
        timeinfo.tm_min,
        timeinfo.tm_sec);
