ubuntu系统下禁用utc时间的设置方法
<p><span><strong>前言</strong></span></p>
<p>
大家在安装双系统以后，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</p>
<p>
<span><strong>原因如下</strong></span></p>
<p>
1、Windows会认为BIOS时间就是你的本地时间</p>
<p>
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。</p>
<p>
<span><strong>更正方法</strong></span></p>
<p>
将ubuntu对待bios时间的方法改为和windows一致。</p>
