[Ubuntu-BR] Servidor NTP

[Jefferson Diego Gomes]

Recomendo deixar esse server aqui:
 server pool.ntp.org

Mas, é normal de inicio as estações não sincronizarem.
Quando você inicia o servidor ntp, ele entra em stratum 16.
Espere de 5 a 10 minutos para ele sincronizar e chegar a stratum 2, daí as estações sincronizarão.
