# Lock customer's timezone selection

#### ✅ What this setting does

When **Lock customer’s time zone selection** is enabled, customers cannot change the time zone on the booking widget.

### ✅ How it works

 When the setting is ON

* The widget shows only one time zone
* Customers cannot switch to another time zone
* All available time slots follow your business time zone

**Example:**

* Your store time zone: **Bangkok, Hanoi (GMT+07:00)**
* Customer is browsing from the US

⇒ The widget still shows times in **GMT+07:00**, and the customer cannot change it.
