系统的时区是系统所在的地理区域。它确定本地时间，用于在系统上显示日期和时间。默认情况下，时区是在安装操作系统期间设置的。但是，如果移动到新位置或在安装过程中时区设置不正确，则可能需要更改时区。
在 Rocky Linux 9 上更改时区
第 1 步。第一步是将系统更新到最新版本的软件包列表。为此，请运行以下命令：
<span class="pln">sudo dnf check</span><span class="pun">-</span><span class="pln">update sudo dnf install dnf</span><span class="pun">-</span><span class="pln">utils</span>
第 2 步。检查您当前的时区。
要检查当前时区，请显示使用以下命令的日期和时间：timedatectl
<span class="pln">timedatectl</span>
输出：
<span class="pun">[</span><span class="pln">root@idroot</span><span class="pun">.</span><span class="pln">us </span><span class="pun">~]#</span><span class="pln"> timedatectl
</span><span class="typ">Local</span><span class="pln"> time</span><span class="pun">:</span> <span class="typ">Mon</span> <span class="lit">2022</span><span class="pun">-</span><span class="lit">12</span><span class="pun">-</span><span class="lit">17</span> <span class="lit">23</span><span class="pun">:</span><span class="lit">46</span><span class="pun">:</span><span class="lit">36</span><span class="pln"> EDT
</span><span class="typ">Universal</span><span class="pln"> time</span><span class="pun">:</span> <span class="typ">Tue</span> <span class="lit">2022</span><span class="pun">-</span><span class="lit">12</span><span class="pun">-</span><span class="lit">18</span> <span class="lit">03</span><span class="pun">:</span><span class="lit">46</span><span class="pun">:</span><span class="lit">36</span><span class="pln"> UTC
RTC time</span><span class="pun">:</span> <span class="typ">Tue</span> <span class="lit">2022</span><span class="pun">-</span><span class="lit">12</span><span class="pun">-</span><span class="lit">18</span> <span class="lit">03</span><span class="pun">:</span><span class="lit">46</span><span class="pun">:</span><span class="lit">36</span>
<span class="typ">Time</span><span class="pln"> zone</span><span class="pun">:</span> <span class="typ">America</span><span class="pun">/</span><span class="typ">New_York</span> <span class="pun">(</span><span class="pln">EDT</span><span class="pun">,</span> <span class="pun">-</span><span class="lit">0400</span><span class="pun">)</span>
<span class="typ">System</span><span class="pln"> clock </span><span class="kwd">synchronized</span><span class="pun">:</span><span class="pln"> yes
NTP service</span><span class="pun">:</span><span class="pln"> active
RTC </span><span class="kwd">in</span> <span class="kwd">local</span><span class="pln"> TZ</span><span class="pun">:</span> <span class="kwd">no</span>
因此，检查时区的另一个选项是使用以下命令检查路径符号链接：ls
<span class="pln">ls </span><span class="pun">-</span><span class="pln">l </span><span class="pun">/</span><span class="pln">etc</span><span class="pun">/</span><span class="pln">localtime</span>
输出：
<span class="pun">[</span><span class="pln">root@idroot</span><span class="pun">.</span><span class="pln">us </span><span class="pun">~]#</span><span class="pln"> ls </span><span class="pun">-</span><span class="pln">l </span><span class="pun">/</span><span class="pln">etc</span><span class="pun">/</span><span class="pln">localtime lrwxrwxrwx</span><span class="pun">.</span> <span class="lit">1</span><span class="pln"> root root </span><span class="lit">18</span> <span class="typ">Dec</span> <span class="lit">17</span> <span class="lit">03</span><span class="pun">:</span><span class="lit">46</span> <span class="pun">/</span><span class="pln">etc</span><span class="pun">/</span><span class="pln">localtime </span><span class="pun">-></span> <span class="pun">../</span><span class="pln">usr</span><span class="pun">/</span><span class="pln">share</span><span class="pun">/</span><span class="pln">zoneinfo</span><span class="pun">/</span><span class="typ">America</span><span class="pun">/</span><span class="typ">New_York</span>
第 3 步。在 Rocky Linux 9 上更改时区。
在更改时区之前，您必须找出要使用的时区的长名称。时区命名约定通常使用“区域/城市”格式。使用命令列出时区：timedatectl
<span class="pln">timedatectl list</span><span class="pun">-</span><span class="pln">timezones</span>
输出：
<span class="pun">[</span><span class="pln">root@idroot</span><span class="pun">.</span><span class="pln">us </span><span class="pun">~]#</span><span class="pln"> timedatectl list</span><span class="pun">-</span><span class="pln">timezones </span><span class="typ">Africa</span><span class="pun">/</span><span class="typ">Abidjan</span> <span class="typ">Africa</span><span class="pun">/</span><span class="typ">Accra</span> <span class="typ">Africa</span><span class="pun">/</span><span class="typ">Addis_Ababa</span> <span class="typ">Africa</span><span class="pun">/</span><span class="typ">Algiers</span> <span class="typ">Africa</span><span class="pun">/</span><span class="typ">Asmara</span> <span class="typ">Africa</span><span class="pun">/</span><span class="typ">Bamako</span> <span class="typ">Africa</span><span class="pun">/</span><span class="typ">Bangui</span> <span class="typ">Africa</span><span class="pun">/</span><span class="typ">Banjul</span> <span class="typ">Africa</span><span class="pun">/</span><span class="typ">Brazzaville</span> <span class="typ">Africa</span><span class="pun">/</span><span class="typ">Bujumbura</span> <span class="typ">Africa</span><span class="pun">/</span><span class="typ">Cairo</span>
滚动列表并找到要设置的时区。例如，要将时区设置为东部标准时间，您会在列表中找到“”。通过输入以下命令设置时区，将“TIMEZONE”替换为要设置的时区：America/New_York
<span class="pln">timedatectl </span><span class="kwd">set</span><span class="pun">-</span><span class="pln">timezone TIMEZONE</span>
例如，要将时区设置为东部标准时间，应输入以下命令：
<span class="pln">timedatectl </span><span class="kwd">set</span><span class="pun">-</span><span class="pln">timezone </span><span class="typ">America</span><span class="pun">/</span><span class="typ">New_York</span>
要验证时区是否已正确设置，请输入以下命令：
<span class="pln">timedatectl</span>
输出：
<span class="pun">[</span><span class="pln">root@server </span><span class="pun">~]#</span><span class="pln"> timedatectl
</span><span class="typ">Local</span><span class="pln"> time</span><span class="pun">:</span> <span class="typ">Tue</span> <span class="lit">2022</span><span class="pun">-</span><span class="lit">12</span><span class="pun">-</span><span class="lit">17</span> <span class="lit">23</span><span class="pun">:</span><span class="lit">42</span><span class="pun">:</span><span class="lit">50</span><span class="pln"> GMT
</span><span class="typ">Universal</span><span class="pln"> time</span><span class="pun">:</span> <span class="typ">Tue</span> <span class="lit">2022</span><span class="pun">-</span><span class="lit">12</span><span class="pun">-</span><span class="lit">18</span> <span class="lit">03</span><span class="pun">:</span><span class="lit">46</span><span class="pun">:</span><span class="lit">53</span><span class="pln"> UTC

<span class="typ">Time</span><span class="pln"> zone</span><span class="pun">:</span> <span class="typ">America</span><span class="pun">/</span><span class="typ">New_York</span> <span class="pun">(</span><span class="pln">GMT</span><span class="pun">,</span> <span class="pun">+</span><span class="lit">0000</span><span class="pun">)</span>
<span class="typ">System</span><span class="pln"> clock </span><span class="kwd">synchronized</span><span class="pun">:</span><span class="pln"> yes
