The lines I marked with >>> above are parts of the problem:
You did not declare "times" to be an array or initialize it as
a pointer, but later use it as an array or initialized pointer.
The argument and return value of time() are supposed to be a pointers
to type time_t, which is not necessarily a long.
You did not use lint before bothering 30,000 people.
