免责声明：我不太擅长使用 Linux，我主要是一名 Windows 管理员。
因此，我的网络上部署了一堆 Raspberry，我面临的问题之一是它们无法保持正确的时间和日期。所以我想我只需安装 NTP 服务并将它们指向我的 Windows 域控制器，它也可以用作 NTP 服务器。但这似乎不起作用。这是我的 ntp.conf 文件：
# /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.
#statsdir /var/log/ntpstats/
statistics loopstats peerstats clockstats
filegen loopstats file loopstats type day enable
filegen peerstats file peerstats type day enable
filegen clockstats file clockstats type day enable
# You do need to talk to an NTP server or two (or three).
# pool.ntp.org maps to about 1000 low-stratum NTP servers. Your server will
# pick a different set every time it starts up. Please consider joining the
# pool: <http://www.pool.ntp.org/join.html>
server 192.168.1.11
#pool 0.debian.pool.ntp.org iburst
#pool 1.debian.pool.ntp.org iburst
#pool 2.debian.pool.ntp.org iburst
#pool 3.debian.pool.ntp.org iburst
# Access control configuration; see /usr/share/doc/ntp-doc/html/accopt.html for
# details. The web page <http://support.ntp.org/bin/view/Support/AccessRestrictions>
# might also be helpful.
#
# Note that "restrict" applies to both servers and clients, so a configuration
# that might be intended to block requests from certain clients could also end
# up blocking replies from your own upstream servers.
# By default, exchange time with everybody, but don't allow configuration.
restrict -4 default kod notrap nomodify nopeer noquery limited
restrict -6 default kod notrap nomodify nopeer noquery limited
# Local users may interrogate the ntp server more closely.
restrict 127.0.0.1
restrict ::1
# Needed for adding pool entries
restrict source notrap nomodify noquery
# Clients from this (example!) subnet have unlimited access, but only if
# cryptographically authenticated.
#restrict 192.168.123.0 mask 255.255.255.0 notrust
# If you want to provide time to your local subnet, change the next line.
# (Again, the address is an example only.)
#broadcast 192.168.123.255
# If you want to listen to time broadcasts on your local subnet, de-comment the
# next lines. Please do this only if you trust everybody on the network!
#disable auth
#broadcastclient
其中 192.168.1.11 是我的 DC/NTP 服务器的 IP。我的配置有问题吗？顺便说一下，当我使用以下命令强制更新时：
ntpdate -u 192.168.1.11
它能工作……但持续时间不长。当我关闭树莓派电源约一小时后再重新启动时，它又回到了错误的时间……NTP 同步不起作用。
编辑：根据要求，这是 ntpq -npcrv 命令的输出：

您的 NTP 源正在使用其自己的本地时钟，这是一个糟糕的时间源，NTP 认为它太远而无法同步。仔细检查中/etc/default/ntp包含的内容（通常，该文件只有一行），然后将 NTP 配置更改为使用适当的外部时间源列表（例如 NTP 池）。-gNTPD_OPTSNTPD_OPTS='-g'192.168.1.11
