I don't think w32time is doing anything at all in that case. If the
workstations are using Windows Networking for their time (which they
should not be in a modern Windows domain configuration) the support for
that pre-dates w32time by a long way. Modern workstations on modern
Windows networks use their own copy of w32time, on port 123.
w32time's main reason for existence is not establishing a correct
absolute time, but for ensuring that times are close enough for
Microsoft's derivative of Kerberos works.
