Chrony: 時刻合わせ
- 同期と確認

Chrony: 時刻合わせ †

CentOS 7から Memo/Linux/ntpの代わりにデフォルトになっている。

第17章 chrony スイートを使用した NTP 設定 - Red Hat Customer Portal
- ntpd と chronyd の違いやメリット等の記載がある。

記事
- 新しいNTPクライアント＆サーバ、chrony - Qiita

同期と確認 †

テスト: 時計を10分前に設定

sudo date -s "$(date -d '10 minutes ago' --iso-8601=seconds)"

時刻の強制同期「ntpdate ntp.nict.jp」相当
```
sudo chronyc makestep
200 OK
```

同期状態の確認
```
chronyc sources
```
