今天升级sys-libs/timezone-data 结果发现提示

ntpdate命令安装:emerge ntp
更新了gentoo后发现系统时间回到2000年1月1号了,再一看硬件时间也是这样。笔记本是2002年买的吧,不知道是不是BIOS电池快没电了, 反正笔记本隔段时间不用就有可能出现这种情况,开机时也显示Low Battery。总结一下如何把时间改回来,以备日后参考。 0. 用date看系统时间,用hwclock --show看硬件时间。 1. 先用ntpdate找一个时间服务器把系统时间调整回来。www.pool.ntp.org提供了很多时间服务器,当然也包括中国的。命令如下, sudo ntpdate 0.cn.pool.ntp.org 2. 用hwclock把系统时间写入到硬件时间(如果只修改系统时间,每次开机系统时间还会改回硬件时间),命令如下, sudo hwclock --systohc 3. 让系统定期从时间服务器更新一下时间。配置/etc/ntpd.conf和/etc/conf.d/ntp-client,然后可以把ntp-client和ntpd加入default run level,命令如下, sudo rc-update add ntpd default sudo rc-update add ntp-client default
