# QuanticRecommendationInterface

> **Note**
>
> This component was introduced in version `2.26.0`.

The `QuanticRecommendationInterface` component initializes the headless recommendation engine and handles localization configurations.
A single instance should be used for each instance of the Coveo Headless recommendation engine.
The `timezone` used in the recommendation engine options is taken from the [Time Zone settings](https://help.salesforce.com/s/articleView?id=admin_supported_timezone.htm&type=5&language=en_US) of the Salesforce org.
It is used to correctly interpret dates in the query expression, facets, and result items.
The `locale` used in the search engine options is taken from the [Supported Locales](https://help.salesforce.com/s/articleView?id=sf.admin_supported_locales.htm&type=5).
Coveo Machine Learning models use this information to provide contextually relevant output.
Moreover, this information can be referred to in query expressions and QPL statements by using the `$locale` object.
