在 Linux 中将 x 秒添加到当前日期 [英] Add x seconds to the current date in Linux

问题描述

我这里有两台 Linux (CentOS 6.0) 机器，我需要在当前日期时间上添加(或删除)5 秒.最后，我的两台机器都会有 5 秒的间隔(一台时间正确，另一台多或少 5 秒).

I have two Linux (CentOS 6.0) machines over here and I need to add (or remove) 5 seconds to the current date time. In the end, both my machines would have a gap of 5 seconds (one with the right time and the other one with 5 seconds more or less).

我知道我可以使用以下命令更改日期:

I know I can change the date with this command:

date -s "DD MMM YYYY HH:MM:SS"

但我需要精确，我很难在正确的时间运行命令.

but I need to be precise and it will be hard for me to run the command at the right time.

所以我想知道一般情况下是否有一种方法可以将当前时间增加 5 秒，这有点像您选择时区而不是格林威治(在我的情况下是 +5 小时).

So I'd like to know if there is a way in general to add 5 seconds to the current time, a bit like when you choose your time zone compared to Greenwich (+5 hours in my case).

推荐答案

您可以使用 date -s "5 seconds" 在一个命令中将当前时间增加 5 秒.

You can add 5 seconds to the current time in one command using date -s "5 seconds".
