CentOS7时间显示不对问题

 今天排查问题的时候查看日志，发现时间不对

[root@centos7-55 bin]# date
Sat Aug 20 05:03:38 EDT 2022

[root@centos7-55 bin]# ntpdate ntp1.aliyun.com

同步一次时间之后再查还是不对

[root@centos7-55 bin]# hwclock --show
Sat 20 Aug 2022 05:04:25 AM EDT -0.178848 seconds

[root@centos7-55 bin]# date
Sat Aug 20 05:05:53 EDT 2022

查看时区，发现是时区设置错误，设置成了纽约时区，应该是装系统的时候忘了设置导致的。

[root@centos7-55 ~]# timedatectl

 重新设置是时区，再查时间OK

[root@centos7-55 ~]# timedatectl set-timezone Asia/Shanghai
[root@centos7-55 ~]# date
