安装双系统以后,发现进入win7和ubuntu系统以后,显示的时间不一致,后来发现是两个系统对硬件时间的看法不一致
1、Windows会认为BIOS时间就是你的本地时间
2、ubuntu默认时间是把BIOS时间当成GMT+0时间,也就是世界标准时,而我国在东八区(GMT+8),所以如果你的Ubuntu位置是中国的话你系统显示的时间就是BIOS时间+8小时。假如现在是早上8点,那么你Ubuntu会显示8点,这时BIOS中的时间是0点。
更正方法:将ubuntu对待bios时间的方法改为和windows一致。
代码:
sudo timedatectl set-local-rtc 1
代码:
$ timedatectl Local time: 六 2016-04-23 09:05:54 CST Universal time: 六 2016-04-23 01:05:54 UTC RTC time: 六 2016-04-23 09:05:54 Time zone: Asia/Shanghai (CST, +0800) Network time on: yes NTP synchronized: no RTC in local TZ: yes 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'.
