time() - Time Date Function
How to get current timing in C++?
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);
int main ()
time ( &ptr );
printf ( "Current local time is::
ctime is: %s", ctime (&ptr) );
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.
