どうすれば正しく時刻を設定できますか？
私は次のことに気づきました：
# sudo ntpdate ptbtime1.ptb.de
4 Jul 20:34:24 ntpdate[12575]: step time server 192.53.103.108 offset -132709448.892320 sec
-132709448.892320秒のオフセットは約4。2年です。このオフセットを削除するにはどうすればよいですか？
私は次の方法で年を増やすことができます：
date --set "1 year"
しかし、私は年を減らすことはできません：
date --set "-1 year"
後者の場合、コマンド日付は「-1年」の前と同じ日付を返します。これはバグですか？
サーバーとして主にKubuntu14.04 LTS（3.13.0-66-generic）。
KDEで時間設定を試しましたが、同じ結果になりました。日時は変更できません。

どのサービスでしょうか？
================================================== ======
/etc/ntp.confに挿入します
tinker panic 0
このオプションが/ etc / default / ntpdateで設定されているかどうかを確認します。
NTPDATE_USE_NTP_CONF=yes
このオプションが/ etc / default / ntpで設定されているかどうかを確認します。
NTPD_OPTS='-g'
ntpを停止し、hwclockを実際の日時に設定するよりも：
# 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をシステムの日付/時刻に設定します（MichaelHamptonに感謝）：
# hwclock -s
まだ異なるhwclock（BIOS時刻）と日付（システム時刻）を確認します。
# hwclock
Sa 09 Jul 2016 18:37:47 CEST -0.984834 Sekunden
# date
Mi 22. Sep 00:24:34 CEST 2027
くださいませNTP再起動して、WAIT約10分。日付またはhwclockで確認できます。日付が間違ったままです！：
# date
Mi 22. Sep 00:29:32 CEST 2027
# date
Mi 22. Sep 00:33:49 CEST 2027
10分後に再起動します。最後のファイルシステムチェックが将来であると文句を言うので、ファイルシステムを修正します。次のようになります。
sudo fsck -v -a /dev/sda1
システム内の将来の日付のファイルを修正します。正しいタイムスタンプを持つ参照ファイルreffileを見つけます。
find / -cnewer /reffile | xargs touch
しばらくの間実行されます。その後再起動すると、すべてが機能するはずです。
多くの方法..例えば
sudo date MMDDhhmmyyyy.ss
# sudo date 02021411971.59
またはあなたはそれをこのようにすることができます
sudo date --set="2016-07-02 13:12:59.990" && date --rfc-3339=ns
または、このように単純に同期することができます
ntpdate -s ntp.ubuntu.com
そして最後にこのようにタイムゾーンを変更します
sudo dpkg-reconfigure tzdata
ここから入手＆ハッピータイム設定
