如何在上传JSch文件到SFTP服务器时保留修改时间

import com.jcraft.jsch.*;

public class SftpUploader {
    public static void main(String[] args) {
        String host = "sftp.example.com";
        int port = 22;
        String username = "your-username";
        String password = "your-password";
        String localFilePath = "path/to/local/file.jsch";
        String remoteFilePath = "path/to/remote/file.jsch";

        JSch jsch = new JSch();
        try {
            Session session = jsch.getSession(username, host, port);
            session.setPassword(password);
            session.setConfig("StrictHostKeyChecking", "no");
            session.connect();

            ChannelSftp channel = (ChannelSftp) session.openChannel("sftp");
            channel.connect();

            channel.put(localFilePath, remoteFilePath, ChannelSftp.OVERWRITE);
            channel.setPreserveTimestamp(remoteFilePath, true);

            channel.disconnect();
            session.disconnect();
        } catch (JSchException | SftpException e) {
            e.printStackTrace();
        }
    }
}
