Here is that TZ value again, this time on standard output so that you
can use the /usr/bin/tzselect command in shell scripts:
Asia/Shanghai
[root@engine ~]#
备份当前的时区配置
[root@engine ~]# mv /etc/localtime /etc/localtime-old
替换系统时区文件
[root@engine ~]# cp /usr/share/zoneinfo/Asia/Shanghai /etc/localtime
或者创建链接文件
[root@engine ~]# ln -sf /usr/share/zoneinfo/Asia/Shanghai /etc/localtime
修改clock系统配置文件/etc/sysconfig/clock为如下内容
[root@swk-204 ~]# cat /etc/sysconfig/clock
ZONE="Asia/Shanghai"
UTC=false #设置为false,硬件时钟不于utc时间一致
ARC=false
[root@swk-204 ~]#
设置操作系统环境变量TZ
在/etc/profile或~/.bashrc文件中设置环境变量TZ
export TZ='Asia/Shanghai'
或者
TZ='Asia/Shanghai'; export TZ
通过source命令即可完成设置
AVA硬编码
import java.util.TimeZone;
import javax.annotation.PostConstruct;
import org.springframework.stereotype.Component;
@Component
public class TimeZoneStartup {
/**
* 设置时区
*/
@PostConstruct
public void init(){
TimeZone.setDefault(TimeZone.getTimeZone("Asia/Shanghai"));
}
}
按照以上方法操作后,可以获取指定的时区
