刚发现去年底也有闰秒

刚翻了翻 /var/log/messages 看到的

Jan  1 07:59:59 cvps-xxx-xxx-xxx-xxx kernel: Clock: inserting leap second 23:59:60 UTC
Jan  1 07:59:59 cvps-xxx-xxx-xxx-xxx systemd: Time has been changed
Jan  1 08:00:01 cvps-xxx-xxx-xxx-xxx chronyd[27652]: System clock status set to not insert/delete leap second

这次闰秒好像很平静，都没出什么问题。
