## Setting Timezone to KST Using timedatectl
When you first install a Linux system or create a cloud instance, the default timezone is often set to UTC. 

Using the timedatectl command, you can check the current timezone and easily change it to KST (Korea Standard Time). 

### 1. Check Current Timezone
First, check the current timezone setting of the system. 
If the `Time zone` field is not Asia/Seoul (KST, +0900), a change is required.
```sh
{
 "title": "Check current timezone"
}
---
$ timedatectl
 Local time: Mon 2026-05-12 03:22:10 UTC
 Universal time: Mon 2026-05-12 03:22:10 UTC
 RTC time: Mon 2026-05-12 03:22:10
//[!code highlight]
 Time zone: Etc/UTC (UTC, +0000)
System clock synchronized: yes
 NTP service: active
 RTC in local TZ: no
```
```adcard
```
### 2. Set Timezone to Asia/Seoul
Use the `timedatectl set-timezone` command to change the timezone to Asia/Seoul.
```sh
{
 "title": "Set timezone to Asia/Seoul"
}
---
$ sudo timedatectl set-timezone Asia/Seoul
```
### 3. Verify the Change
Once the change is complete, verify that KST is correctly applied using the `timedatectl` and `date` commands.
```sh
{
 "title": "Verify timezone with timedatectl"
}
---
$ timedatectl
 Local time: Mon 2026-05-12 12:22:31 KST
 Universal time: Mon 2026-05-12 03:22:31 UTC
 RTC time: Mon 2026-05-12 03:22:31
//[!code highlight]
 Time zone: Asia/Seoul (KST, +0900)
System clock synchronized: yes
 NTP service: active
 RTC in local TZ: no
```
```sh
{
 "title": "Verify timezone with date"
}
---
$ date
//[!code highlight]
Mon May 12 12:22:35 KST 2026
```
You can now confirm that the system time is correctly set to KST (+0900).
