Bem, antes de tudo, não custa ter certeza de que você tem conectividade v6 ao 
servidor a.ntp.br

$ ping6 a.ntp.br
PING6(56=40+8+8 bytes) 2001:12ff:0:2::4 --> 2001:12ff::8
16 bytes from 2001:12ff::8, icmp_seq=0 hlim=62 time=0.569 ms
16 bytes from 2001:12ff::8, icmp_seq=1 hlim=62 time=0.666 ms
16 bytes from 2001:12ff::8, icmp_seq=2 hlim=62 time=0.600 ms
