Dear Expert,

I have implemented the latest Zabbix appliance from the official download page. Per documentation, I have changed the timezone via the following two steps:
1. cp /usr/share/zoneinfo/Asia/Shanghai /etc/localtime
2.Frontend timezone was set to Asia/Shanghai in /etc/apache2/conf-available/zabbix.conf

But both the time on the server and front-end shows incorrectly, after many tries by the online tips, it still cannot be fixed.

I had tried two other extra ways: 1. change the time manually; 2. Synchronize the hardware and software clock. Both ways would lead to "The remote system refused the connection.", only after reinstalling the appliance would make me go to command line again.

For the kind assistance. Tons of thanks!
