RedHat 8 time synchronization and time zone modification

In the new RedHat 8 Or updated Linux In the version , We can use

timedatectl

To make some modifications to the time related operations .

Set time zone

When the system is initialized , Setting the time is very necessary , You can use the following method to modify the time zone .

for example , If you want to change the time zone to US Eastern time , Run the following command directly ：

timedatectl set-timezone America/New_York

That's all right. .

Set up NTP Sync

before , We still need to pack a lot of NTP Service to synchronize time .

Now just run ：

timedatectl set-ntp yes

You can set up automatic synchronization .

Is it very convenient .
