Bitcoin should absolutely not be sending the computer’s time to the network. Nor should it depend on the clock being set properly. Each node can keep track of when they see transactions come through. If they want to reject a block because it contains a transaction they saw too long ago, then they are free to reject it; no reason for the nodes to compare each other’s clocks. If it’s too old they will all reject it, which is what we want.
