If you are getting that error message, consider replacing your operating
system with one written by someone who knows English.

#include<stdlib .h>
#include<stdio. h>

void main(void)
Stop right there. main returns int. If you define main as having any other
return type, the C language disowns your program completely, and does not
define what will happen.
{
int p;

p=system("time" );

if(p<0)

The meaning of the return value of system() is implementation-dependent.
Check your documentation.

There is no reason why it should. It is not a valid C program.

Here's what I say in return - I compiled it successfully and changed my
system's time and clock successfully.

You'll get better results if you don't write like an idiot.
#include<stdlib .h>
#include<stdio. h>

void main(void)
Oops, not a valid C program once you define main() with a return type
of void instead of int.
{
int p;

p=system("time" );

if(p<0)
{
perror("Error:" );
exit(1);
}
}

Make an effort to use proper spelling and grammar, and get rid of the
stupid abbreviations and SMS chat usage.

Then go back and read the answers you got when you posted the same
question yesterday. Especially the one by Madhav.

That's as may be, but it is still not a valid C program.

I very much doubt your computer printed that message.

(top tip: in CLC do not use abbreviations of words, this is not a
mobile phone / IM).

As for your code:
a) main returns an int, not void. Returning anything other than an int
is not well defined and may not work.

b) the return value of system is implementation defined, you can't
check it like that.

c) you may not be able to execute 'time' like that - eg on MSDOS &
Windows its a builtin shell command so you may need to invoke the
shell first. For more info, ask in a Windows programming group as the
precise details of that are offtopic here.

Learn to write English. Pay more attention writing C code. The following
works as I expect on my machine. How about yours?

#include<stdlib .h>
#include<stdio. h>

int main(void) {
int p;
p = system("time");

if (p < 0) {
perror("Error:" );
exit(1);
}
return 0;
}
