ShedLock - Not Executing on Kubernetes

Question

I'm using Shedlock version 4.22.0 with JDBC integration. I have one configuration class

@Configuration
@EnableScheduling
@EnableSchedulerLock(defaultLockAtMostFor = "PT30S")
public class ShedLockConfiguration {
   @Bean
   public LockProvider lockProvider(DataSource dataSource) {
        return new JdbcTemplateLockProvider(dataSource);
   }
}

For execution I'm using annotation @SchedulerLock eg.

@SchedulerLock(name = "MyTask", lockAtMostFor = "PT1M", lockAtLeastFor = "PT1M")

Everything works perfectly on a local PC but when app is deployed on Kubernetes (AKS), no task are triggered. Logs are empty. App after startup does nothing

I added also debug to spring configuration on

logging:
  level:
    net.javacrumbs.shedlock: DEBUG

Nothing is logged

Execution should be triggered by a @Scheduled annotation. ShedLock only prevents parallel task execution, it does not schedule anything. If you have the @Scheduled annotation, check the shedlock table in the DB as described in troubleshooting.

I solved issue. The problem was with timezone on server. Task was locked 1h ahead because of diffrent timezone on my local PC. I removed all rows from shedlock table
