How to Handle Time Zone Conversion with JPA and Hibernate?

Handling Time Zone Conversion with JPA and Hibernate

When storing and retrieving date/time values with JPA and Hibernate, it is crucial to consider time zone handling to ensure accurate data management.

Configuring UTC Time Zone with Hibernate 5.2 and Above

To force the storage and interpretation of date/time values in UTC time zone, Hibernate 5.2 introduces a configuration property:

• hibernate.jdbc.time_zone: Set this property to "UTC" to enforce UTC time zone.

Add the following property to your properties.xml configuration file:

<property name="hibernate.jdbc.time_zone" value="UTC"/>

For applications using Spring Boot, include the property in your application.properties file:

spring.jpa.properties.hibernate.jdbc.time_zone=UTC

This configuration ensures that the date/time values stored in the database and retrieved by JPA are always interpreted as UTC. For example, a Pacific Standard Time (PST) value of 9:30am will be stored in the database as 5:30pm UTC and retrieved as such, regardless of the local time zone of the server.
