问COS上传对象后生成的URL时提供的过期时间最长支持多久？

//生成客户端
COSClient cosClient = new COSClient(cred, clientConfig);
//上传对象
PutObjectRequest putObjectRequest = new PutObjectRequest(bucketName, key, localFile);
PutObjectResult putObjectResult = cosClient.putObject(putObjectRequest);
//生成访问对象的URL
//设置过期时间 一小时
Date expiredTime = new Date(System.currentTimeMillis() + 3600L * 1000L);
//生成URL
URL url = cosClient.generatePresignedUrl(bucketName, key, expiredTime);
System.out.println(url.toExternalForm());
