我使用的是慢速连接（拨号连接），延迟时间很长（+400ms）。我最近收到了一台坏了的 MyBook World，我把它翻新了，并在它上面安装了 Debian。
问题是，该设备没有内置时钟，因此每次启动时日期都会被设置回 1970 年。我本以为可以使用 NTP 解决这个问题，但 NTP 运行一段时间后就会退出，没有错误，时间也一样。我使用的是ntp -q。
我也尝试过ntpdate-debian，但出现以下错误：
1 月 1 日 00:14:11 ntpdate[966]: 未找到适合同步的服务器
这是我的ntp.conf：
root@mybook:~# cat /etc/ntp.conf
# /etc/ntp.conf, configuration for ntpd; see ntp.conf(5) for help
driftfile /var/lib/ntp/ntp.drift
# Enable this if you want statistics to be logged.

如您所见，我也尝试选择地理位置靠近我（比利时）的服务器。
有人可以提供一些帮助吗？

尝试使用ntpdatebefore ntp。您还可以使用ntpq -c peers命令查看是否正在连接到服务器。如果可能，我通常使用我的 ISP 时间服务器或 DNS 服务器。看起来您可能正在这样做。这些应该具有良好的连接性和延迟。
ntpdate -d ntp3.linocomm.net可用于检查连接性。您可以在一个命令中列出所有服务器。删除 -d 以设置时间。
