One problem but it's probably not your error is that making time long will not force the calculation on the right of the = to be done as long. C only looks at the participants in the equation to decide how to do the arithmetic, not what you're assigning the result to. So again, you need to cast one of one of the leading values on the right side as (long) or use 1000L. C will call 1000 an int and 1000L is a long.
How are you displaying time to know it's zero? Are you still using the %d specifier in your printf? I can't remember if the PICs are little endian or big endian. If they're big endian, you'll only see the high order half of the long value which in this case is zero.
