LightAdmin - Customise parsing DateTime with app timezone - spring-mvc

Question

I am using LightAdmin 1.1.0.Snapshot with Spring Boot. I am using Joda DateTime to represent time with zone.
I can see LightAdmin captures date-time in UTC and Default Deserialization context used for parsing data is by UTC in LightAdmin. From debugging, I see LightAdmin uses its own ObjectMapper and MessageConverters using LightAdminRestMvcConfiguration, so it is not using the Spring Boot global overriders for customising the Jackson2ObjectMapperBuilder like the one below.
#Bean
public Jackson2ObjectMapperBuilder jacksonBuilder() {
Jackson2ObjectMapperBuilder builder = new Jackson2ObjectMapperBuilder();
builder.timeZone(coreProperties.appTimeZone());
return builder;
}
Any help on how to 1) override settings for Jackson in LightAdmin to parse with default app timezone or 2) Handle Json serialization / converter outside LightAdmin to solve this problem differently. Any help would be awesome.
Thanks,
Alex

One way I solved the problem is to reconfigure the LightAdmin beans after the context is loaded using the below.
#Component
public class AppContextListener implements ApplicationListener<ContextRefreshedEvent>{
#Inject
CoreProperties coreProperties;
#Override
public void onApplicationEvent(ContextRefreshedEvent event) {
GenericWebApplicationContext appContext = getRootApplicationContext(event);
WebApplicationContext lightAdminWebContext = getWebApplicationContext(appContext.getServletContext(), LightAdminWebApplicationInitializer.SERVLET_CONTEXT_ATTRIBUTE_NAME);
lightAdminWebContext.getBeansOfType(ObjectMapper.class).values().stream()
.forEach(objectMapper -> objectMapper.setTimeZone(coreProperties.appTimeZone()));
}
private GenericWebApplicationContext getRootApplicationContext(ContextRefreshedEvent event) {
return (GenericWebApplicationContext) (event.getApplicationContext().getParent() != null ? event.getApplicationContext().getParent() : event.getApplicationContext());
}
}
