time() - Time Date Function

How to get current timing in C++?


time() is used to get the current calendar timing and date of the system. If the system time is not available "-1" is returned. This function can be called with a "NULL" pointer or with a pointer to a "time_t" variable.


time_t time( time_t *time);

Example :

#include <stdio.h>
#include <time.h>
int main ()
time_t ptr;
time ( &ptr );
printf ( "Current local time is::
ctime is: %s", ctime (&ptr) );
return 0;

Result :

Current local time is:: Mon Mar 09 13:05:10 2010

In the above example "time()" uses a "time_t" pointer, so that it is used with the "ctime()" to get the current local timing and date.
