前言
大家在安裝雙系統(tǒng)以后,發(fā)現(xiàn)進(jìn)入win7和ubuntu系統(tǒng)以后,顯示的時(shí)間不一致,后來(lái)發(fā)現(xiàn)是兩個(gè)系統(tǒng)對(duì)硬件時(shí)間的看法不一致
原因如下
1、Windows會(huì)認(rèn)為BIOS時(shí)間就是你的本地時(shí)間
2、ubuntu默認(rèn)時(shí)間是把BIOS時(shí)間當(dāng)成GMT+0時(shí)間,也就是世界標(biāo)準(zhǔn)時(shí),而我國(guó)在東八區(qū)(GMT+8),所以如果你的Ubuntu位置是中國(guó)的話你系統(tǒng)顯示的時(shí)間就是BIOS時(shí)間+8小時(shí)。假如現(xiàn)在是早上8點(diǎn),那么你Ubuntu會(huì)顯示8點(diǎn),這時(shí)BIOS中的時(shí)間是0點(diǎn)。
更正方法
將ubuntu對(duì)待bios時(shí)間的方法改為和windows一致。

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'.
