            $.ajax({
              url: 'get_beijing_time.php',
              dataType: 'json',
              success: function(data) {
                // 检查是否成功获取时间戳
                if (data && data.data && data.data.t) {
                  var timestamp = Math.floor(data.data.t / 1000); // 去掉毫秒部分
                  var beijingTime = new Date(timestamp * 1000); // 转换成 JavaScript 时间对象
                  // 格式化年月日时分秒
                  var year = beijingTime.getFullYear();
                  var month = ("0" + (beijingTime.getMonth() + 1)).slice(-2);
                  var day = ("0" + beijingTime.getDate()).slice(-2);
                  var hours = ("0" + beijingTime.getHours()).slice(-2);
                  var minutes = ("0" + beijingTime.getMinutes()).slice(-2);
                  var seconds = ("0" + beijingTime.getSeconds()).slice(-2);
                  // 将年月日时分秒显示在页面上
                  $('#beijingTime').text(year + "-" + month + "-" + day + " " + hours + ":" + minutes + ":" + seconds);
                } else {
                  console.error('Failed to fetch Beijing time.');
                }
              },
              error: function(xhr, status, error) {
                console.error('Error fetching Beijing time:', error);
              }
            });
          }
          function updateLocalTime() {
            // 获取本地时间
            var localTime = new Date();
            // 格式化年月日时分秒
            var year = localTime.getFullYear();
            var month = ("0" + (localTime.getMonth() + 1)).slice(-2);
            var day = ("0" + localTime.getDate()).slice(-2);
            var hours = ("0" + localTime.getHours()).slice(-2);
            var minutes = ("0" + localTime.getMinutes()).slice(-2);
            var seconds = ("0" + localTime.getSeconds()).slice(-2);
            // 将年月日时分秒显示在页面上
            $('#localTime').text(year + "-" + month + "-" + day + " " + hours + ":" + minutes + ":" + seconds);
          }
          // 页面加载时更新北京时间
          getBeijingTime();
          // 每秒更新一次北京时间
          setInterval(getBeijingTime, 1000);
          // 每秒更新一次本地时间
          setInterval(updateLocalTime, 1000);
