以下内容是关于帮助你在Linux下设置日期和时间的一些步骤,也包含了一点ntpd时间同步的内容。特别提醒的是在发行版本的限制是red hat系列,包括fedora,centos,redflag,unbreakable linux等。
There are two clocks to configure in Linux, the hardware clock and the system clock. The hardware clock determines the system clock on system boot. While the system is running, changes to one of these doesn't affect the other.
在Linux下有两个时钟需要配置,硬件时钟和系统时钟。硬件时钟在系统启动时决定系统时钟,当系统处于运行状态下时,修改其中任何一个并不能对另一个默认生效。
Note: it's best to set the hardware clock and have the system clock be set upon a reboot. Changing the system clock by using the date program on a running system could cause date discontinuities and consequently problems. If you will be using ntpd, you probably don't need to set either of these clocks (unless the current time is more than 1000s off the real time). Just setup ntpd and let ntpd adjust the time (it will do it in small steps to keep system timestamps reliable).
现在大部分的发行版本在图形界面下都提供了时钟设置工具,例如kde,gnome都有友好的 图形化工具,这里就不多说了。
You can use timeconfig to configure the timezone and UTC settings. Timeconfig will update /etc/sysconfig/clock and /etc/localtime.
Set the time zone manually if not already set.
Linux uses the file /etc/localtime to determine the time zone. This file should be either a copy of the appropriate timezone file from the directory /usr/share/zoneinfo or a symbolic link. If your time zone is incorrect, create a symbolic link to the appropriate timezone file.
