The NTP (Network Time Protocol) is an Internet protocol that is used to synchronize the time on your system with a centralized Network Time Protocol server. It also analyses the timestamp values including the frequency of errors and the stability.

```
Display a particular Time zone under Asia starting with the alphabet H.
```
# timedatectl list-timezones | grep  -o "Asia/H.*"
```
To change or set a Time zone you can use the below command. E.g. Change to Hong Kong.
```
# timedatectl set-timezone Asia/Hong_Kong
```
To enable NTP to synchronize time with Internet time.
```
# timedatectl set-ntp yes
```
