How to get appropriate timestamp in c for logs?

Question

I'm creating a client-server application. I want to do some logging.

Server is in C. Now I'm print messages to the terminal. So I'll probably just copy that to sprintf and add timestamp. How can I do that timestamp? It should probably include date, hours, minutes, seconds.

Please find the thread safe version of Pavan's answer below.

time_t ltime;
struct tm result;
char stime[32];

ltime = time(NULL);
localtime_r(&ltime, &result);
asctime_r(&result, stime);

Please refer to this for more details.
