wtime.net has an inconsistent DNS configuration, and you should *expect*
something to fail. From the .net name servers:

wtime.net.              2D IN NS        NS.JCITY.NET.
wtime.net.              2D IN NS        NS.wtime.net.

NS.JCITY.NET.           2D IN A         210.217.192.1
NS.wtime.net.           2D IN A         211.116.92.5

Asking 210.217.192.1, we find only *one* name server:

wtime.net.              1H IN NS        ns.wtime.net.
ns.wtime.net.           1H IN CNAME     tdc_srv1.wtime.net.
tdc_srv1.wtime.net.     1H IN A         211.116.92.5

and it is an alias - which is illegal. The name server at 211.116.92.5
responds the same way.

Fix the DNS configuration - and if FreeBSD *still* fails we can investigate.
