I don't really see where you're using a time function to pull the current time, and also it looks like your function prototype is int and looking for int input, but when you actually put together you function is a double.

// your prototype
int time (int);

//your function
double time (double t)
{
double time;
t = time;
if (t <= 17.00)
{
cout<<"Early";
}
else
{
cout<<"Late";
}

return time;
}

also I've been playing around with ways to make it compare times... you should check out
http://www.cplusplus.com/reference/clibrary/ctime/difftime/
and combine it with
http://www.cplusplus.com/reference/clibrary/ctime/mktime/
I'm a bit of a newb, so I didn't put together anything spectacular here, but I figured since no one had answered you yet I would throw in my 2 cents, for what it's worth.

Well, the program seems to compile. But there is a great deal wrong with it.
For example, this line: cout<<pass;
What does it do? It outputs the address of the function called pass().

Perhaps a review of the use of functions would be a good plan:
