#### 概述

在日常巡检中发现系统日志和java服务日志与系统时间不一致问题。

#### 解决思路

##### 查看时区是否异常

```shell
[root@46 phase2]# date -R
Mon, 09 Aug 2021 10:24:24 +0800
[root@46 phase2]# timedatectl
      Local time: 一 2021-08-09 10:24:34 CST
  Universal time: 一 2021-08-09 02:24:34 UTC
        RTC time: 一 2021-08-09 02:24:34
       Time zone: Asia/Shanghai (CST, +0800)
     NTP enabled: yes
NTP synchronized: yes
 RTC in local TZ: no
      DST active: n/a
```

如时区不为+0800则替换配置

```shell
ln -sf /usr/share/zoneinfo/Asia/Shanghai /etc/localtime
```

##### 系统日志时间不一致

查看/var/log/messages 日志内容发现时间与系统时间不一致

```shell
Aug  9 02:06:58 46 dbus-daemon: dbus[991]: [system] Activating via systemd: service name='org.freedesktop.timedate1' unit='dbus-org.freedesktop.timedate1.service'
Aug  9 02:06:58 46 dbus[991]: [system] Activating via systemd: service name='org.freedesktop.timedate1' unit='dbus-org.freedesktop.timedate1.service'
Aug  9 02:06:58 46 systemd: Starting Time & Date Service...
Aug  9 02:06:59 46 dbus[991]: [system] Successfully activated service 'org.freedesktop.timedate1'
Aug  9 02:06:59 46 dbus-daemon: dbus[991]: [system] Successfully activated service 'org.freedesktop.timedate1'
Aug  9 02:06:59 46 systemd-timedated: /etc/localtime should be a symbolic link to a time zone data file in /usr/share/zoneinfo/.
Aug  9 02:06:59 46 systemd: Started Time & Date Service.
Aug  9 02:07:50 46 systemd: Starting Time & Date Service...
Aug  9 02:07:50 46 systemd-timedated: /etc/localtime should be a symbolic link to a time zone data file in /usr/share/zoneinfo/.
Aug  9 02:07:50 46 systemd: Started Time & Date Service.
[root@46 ~]# date
2021年 08月 09日 星期一 10:22:25 CST
```

重启系统日志服务

```shell
systemctl restart rsyslog
```

##### java服务日志时间异常

查看java服务进程日志时间也不一致，新建或修改/etc/sysconfig/clock配置为如下内容：

```shell
# The time zone of the system is defined by the contents of /etc/localtime.
# This file is only for evaluation by system-config-date, do not rely on its
# contents elsewhere.
ZONE="Asia/Shanghai"
UTC=false
ARC=false
```

重启系统后正常。
