Si je peux me permettre, tous les serveurs donné sont des serveurs primaires. On doit donc éviter de les utiliser en tant qu'individu. Ils sont plus la pour synchroniser les serveur ntp de sociétés ou de groupements. Je conseillerais plus l'utilisation de ntp.tuxfamily.net qui est dédié aux utilisateurs finaux

Non les NTP Primaires sont disponibles pour la synchro des serveurs de strate 2 ou 3. Tu dois synchroniser ton poste ou ton reseau avec un strate 2 ou 3 uniquement, ... (Pour nous ca ne change pas grd chose) Respecter cette regle permet de conserver des serveurs NTP libres d'accès a tt le monde ... Enfin pour la syncrho on n'utilise jamais le nom DNS (Sauf mention contraire), le nom est donne a titre indicatif et permet au proprietaire de garantir le service

Cherche server ntp qui marche !
