Hi:

How does one obtain the current date and time on a UNIX system from inside a C
program ?

  gettimeofday(struct timeval *, struct timezone *);

gives me the  time since the start of the epoch. Is there a easier way to
obtain the current system time like date(1) does ?

Thanks,

check man localtime(). This is the basic call, and the man page
should list variants and formaters.

You can use the time() function to get the number of seconds
since the epoch and pass that value to ctime() to get a string.

Thanks to the folk who replied. The solution was to use

#include<time.h>
time_t t = time(0);
printf("%s"ctime(&t));

If you are on a SVR4 system have a look at the ctime(3) manual page.

This has all the routines to get the current date/time in a variety of
formats.

I don't know if this is available on other systems, but have a look for it
anyway, you might be lucky.
