$ timedatectl Local time: 金 2019-11-15 16:28:34 UTC Universal time: 木 2019-11-14 16:28:34 UTC RTC time: 木 2019-11-14 16:28:34 Time zone: UTC (UTC, +0000) System clock synchronized: yes systemd-timesyncd.service active: yes RTC inlocal TZ: no
ここで確認したいのは
タイムゾーン
RTCへLocal Timeを同期するか
です。
タイムゾーンはUTC、RTCへLocal Timeを同期しない設定となっています。
そのため、次にWindowsを起動した際にはRTCの時刻がズレた状態となります。
タイムゾーンをJSTにする
JSTとは日本時間の事です。
次のコマンドでタイムゾーンを日本時間に変更します。
1
$ timedatectl set-timezone Asia/Tokyo
念の為、設定が変わった事を確認します。

$ timedatectl Local time: 金 2019-11-15 01:35:59 JST Universal time: 木 2019-11-14 16:35:59 UTC RTC time: 木 2019-11-14 16:35:59 Time zone: Asia/Tokyo (JST, +0900) System clock synchronized: yes systemd-timesyncd.service active: yes RTC inlocal TZ: no
RTCに同期する時刻をLocal Timeにする
次のコマンドでRTCにLocal timeを同期させる設定を行います。

Warning: The system is configured to read the RTC time in the local time zone. This mode can not be fully supported. It will create various problems with time zone changes and daylight saving time adjustments. The RTC time is never updated, it relies on external facilities to maintain it. If at all possible, use RTC in UTC by calling 'timedatectl set-local-rtc 0'.

$ ls sakkuntyo-mint sakkuntyo-mint.pub
.pubが付いているのが公開鍵 ついていないのが秘密鍵
GitHubに配置する
github.comのsettingsを開く
「SHS and GPG keys」を開き、公開鍵の名前と公開鍵の内容を登録
Titleは何でも大丈夫
これで公開鍵が登録されました
sshクライアントにgitの設定を追加
~/.ssh/configを編集し、以下の4行を追加
1 2 3 4
Host git hostname github.com user git identityfile ~/.ssh/sakkuntyo-mint #秘密鍵のパス
