Binance Crypto Exchange API错误‘-1021=此请求的时间戳在recvWindow之外’Error php curl？

<?php
$apiUrl = 'https://api.binance.com/api/v3/time';
$recvWindow = 5000; // 设置合理的recvWindow值，单位为毫秒

// 发送请求获取服务器时间戳
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $apiUrl);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
$response = curl_exec($ch);
curl_close($ch);

// 解析服务器返回的时间戳
$result = json_decode($response, true);
$serverTimestamp = $result['serverTime'];

// 同步本地时间
$localTimestamp = time();

// 计算时间戳差值
$timestampDiff = $localTimestamp - $serverTimestamp;

// 发送实际的API请求
$apiUrl = 'https://api.binance.com/api/v3/your-endpoint';
$timestamp = $localTimestamp - $timestampDiff;
$queryString = http_build_query(['timestamp' => $timestamp, 'recvWindow' => $recvWindow]);
$apiUrl .= '?' . $queryString;

$ch = curl_init();
