'Network Time Protocol

In a distributed system two nodes A and B want to synchronize their clocks. The communications delay along the link A to B is 40ms and along B to A is 20 ms.

These delays are unknown to A and B. These nodes use Cristian's algorithm to synchronize their clocks. Node A's clock is 500 ms and B's clock is 632ms.

And the node A is initiator. After completion, what is the time that A shows?
