Handle Date data type with spring data ldap

Question

I am using spring-data-ldap to find all the users who are created or modified in a certain date range. My UserRepository

package com.test.service.ldap.com;

import org.springframework.data.ldap.repository.LdapRepository;
import org.springframework.stereotype.Repository;

import java.util.List;

@Repository
public interface UserRepository extends LdapRepository<User> {}

My User class

package com.test.service.ldap.com;

import lombok.Data;
import lombok.ToString;
import org.springframework.data.domain.Persistable;
import org.springframework.ldap.odm.annotations.Attribute;
import org.springframework.ldap.odm.annotations.Entry;
import org.springframework.ldap.odm.annotations.Id;
import org.springframework.ldap.odm.annotations.Transient;

import javax.naming.Name;
import java.util.Date;

    @Entry(base = "ou=people,dc=example,dc=com",objectClasses = { "top","person","organizationalPerson","inetOrgPerson" })
    @Data
    @ToString
    public final class User implements Persistable<Name> {
    
        private @Id Name id;
        private @Attribute(name = "cn") String firstname;
        private @Attribute(name = "sn") String lastname;
        private @Attribute(name = "mobile") String mobile;
        private @Attribute(name = "createTimestamp") Date createdtime;
        private @Attribute(name = "modifyTimestamp") Date modifiedtime;
    
        @Transient
        private Boolean isNew = false;
    
        @Override
        public boolean isNew() {
            return isNew;
        }
    }

I get the below exception when I try to findAll()

org.springframework.core.convert.ConversionFailedException: Failed to convert from type [java.lang.String] to type [java.util.Date] for value '20221229074251.850Z'

I want to know

1. How to handle Date data type in spring-data-ldap
2. Can I use something like findAllOrderByModifiedTimeDesc or use Between two dates
