如何在Arch Linux中固定时间

Question

目前，我在我的桌面上使用Arch作为操作系统。当我看我的时间，是22:38，时间显然是17:08左右。当我调用命令timedatectl时，我得到：

Local time: Wed 2017-01-11 22:37:43 IST
Universal time: Wed 2017-01-11 17:07:43 UTC
    RTC time: Wed 2017-01-11 17:07:41
    Time zone: Asia/Kolkata (IST, +0530)
Network time on: yes
NTP synchronized: no
RTC in local TZ: no

更新

当我运行sudo systemctl status systemd-timesyncd时，我得到：

● systemd-timesyncd.service - Network Time Synchronization
   Loaded: loaded (/usr/lib/systemd/system/systemd-timesyncd.service; enabled; vendor preset: enabled)

traceroute

我还尝试了命令traceroute -U -p ntp pool.ntp.org，我得到：

我该怎么解决这个问题？我甚至试过timedatectl set-ntp true。我应该重新启动才能生效吗？

Answer 1

时区对你的位置正确吗？并且您应该通过timedatectl设置时区来设置正确的时区。

date命令显示当前位置的系统时间。

ntpdate将为您的时区修正时间。

例如，使用apple服务器将产生如下结果：

sudo ntpdate time.apple.com

11 Jan 19:18:28 ntpdate[1052]: adjust time server 17.253.38.125 offset 0.004981 sec
