我的服务器位于未来 2027 年：
# sudo ntpdate ptbtime1.ptb.de
9 Jul 00:04:01 ntpdate[10000]: step time server 192.53.103.108 offset -353547847.989546 sec
# date
Di 21. Sep 23:48:18 CEST 2027
# hwclock
Sa 09 Jul 2016 02:03:56 CEST -0.234935 Sekunden
漂移非常大，而且还有 10 多年的时间。我无法通过“正常”重置来改变漂移。我已经阅读了几篇文章，并尝试了很多方法，例如ntpdate –b，ntpd-gq 命令或者修补恐慌 0。我更改了时区，并尝试手动设置日期/时间。但没有任何效果。我该如何纠正这个问题？有人能帮我吗？我正在运行 Kubuntu 14.04 LTS（GNU/Linux 3.13.0-66-generic i686）
==================================================================
这会引起问题吗？
# sudo service ntp stop
* Stopping NTP server ntpd [ OK ]
# ntpq -p
ntpq: read: Connection refused
==================================================================
# sudo service ntp stop
* Stopping NTP server ntpd [ OK ]
# sudo ntpd -gq
ntpd: time set -353547849.485594s
# sudo service ntp start
* Starting NTP server ntpd [ OK ]
# date
Mi 22. Sep 11:39:09 CEST 2027
====================================================================
请注意对于 ntpd 来说，距离“太远”有多远？它能通过突然跳到重负载来达到这个距离吗？这能被覆盖吗？“根据手册页，如果您的时钟偏差超过 1000 秒，ntpd 将无法工作。”
====================================================================
我尝试手动更改它：
# date
Mi 22. Sep 11:32:09 CEST 2027
# sudo date --set="2016-07-09 11:50:59.990"
Sa 9. Jul 11:50:59 CEST 2016
# date
Mi 22. Sep 11:35:08 CEST 2027
==================================================================
我可以用日期——设置“-1年”。但我没法减少它。
=========================================================================
它不起作用：
# sudo service ntp stop
* Stopping NTP server ntpd [ OK ]
# sudo ntpdate-debian
9 Jul 14:56:52 ntpdate[3684]: step time server 131.188.3.220 offset -353547850.182477 sec
# sudo service ntp start
* Starting NTP server ntpd [ OK ]
# date
Mi 22. Sep 14:41:25 CEST 2027
更新：我没有足够的耐心。我不得不再等一秒钟，但巨大的漂移仍然存在。

我也尝试了 sntp

=====================================================
已删除的漂移文件：
sudo service ntp stop
rm /etc/adjtime
rm /var/lib/ntp/ntp.drift
shutdown –h now
重启后 /var/lib/ntp/ntp.drift 为空。/etc/adjtime 为
0.000000 1821611426 0.000000
1821611426
UTC
日期/时间仍然相同。漂移存储在哪里？

我停止了 ntp（用 检查ps –aux | grep ntp）并使用hwclock –s：
# sudo service ntp stop
* Stopping NTP server ntpd [ OK ]
# sudo hwclock --set --date="7/9/16 18:37:30"
# hwclock
Sa 09 Jul 2016 18:37:34 CEST -0.047338 Sekunden
# hwclock -s
# hwclock

# date
Mi 22. Sep 00:29:32 CEST 2027
# date
Mi 22. Sep 00:33:49 CEST 2027
我必须重新启动并且必须更正文件系统，因为它抱怨最后一次文件系统检查是在将来。
非常感谢所有帮助过我的人，特别感谢迈克尔！！！

由于您正在运行基于 Debian 的发行版，请尝试以下操作：
sudo service ntp stop
sudo ntpdate-debian
sudo service ntp start
