I am creating/installing a second NW6.5 server into an existing network.
At the eDirectory Installation screen where you specify the tree and
container to install to, selecting next results in the warning "It
appears time on this server is not synchronized to the network." It
recommends retrying by going back a step and trying again, but the
result is the same.

How do I get the time to synchronize? (This server's time is about 28
minutes behind.)
