For a Hong Kong server, correct time settings can not only help us better manage the server, but also ensure that our applications can run normally. How to modify the time on a Hong Kong server? This article will give you a detailed introduction.

　　How to modify the time on a Hong Kong server

　　Check the current system time

　　We need to check the current system time on the Hong Kong server. In the Linux system, we can use the following command to check the current system time:

　　date

　　In the Windows system, we can right-click the time in the lower right corner of the taskbar, select "Adjust date/time", and then check the current system time.

　　Modify system time

　　sudo date -s "2022-01-01 12:34:56"

　　Note: This command requires administrator privileges, so we need to use the sudo command. The date and time format must match the format accepted by the date command. In this example, the format we use is "YYYY-MM-DD HH:MM:SS".

　　1. Question: Why does the time return to the original time after restarting the server after modifying the system time in the Linux system?

　　Answer: This may be because the startup script of the Linux system is not configured correctly. We can try to edit the /etc/rc.local file and add a line of command to automatically set the system time. date -s "2022-01-01 12:34:56". In this way, every time the server is restarted, this command will be automatically executed to set the system time.

　　2. Question: Why do some applications still display the wrong time after modifying the system time in the Windows system?

　　A: This may be because some applications use the local computer's system time instead of the network time. We can try to change the settings of these applications to use the network time. The specific method depends on the specific settings of these applications.

　　3. Question: How to view the current time zone in Linux system?

　　A: We can use the timedatectl command to view the current time zone. timedatectl status, this command will display the name and offset of the current time zone.
