找到报错的地方：  
frameworks\\base\\core\\ java\\android\\net\\SntpClient.java

/** * Sends an SNTP request to the given host and processes the response. * * @param host host name of the server. * @param timeout network timeout in milliseconds. * @param network network over which to send the request. * @return true if the transaction was successful. */
    public boolean requestTime(String host, int timeout, Network network) { 
        final Network networkForResolv = network.getPrivateDnsBypassingCopy();
        InetAddress address = null;
        try { 
            address = networkForResolv.getByName(host);
        } catch (Exception e) { 
            EventLogTags.writeNtpFailure(host, e.toString());
            if (DBG) Log.d(TAG, "request time failed: " + e);
            return false;
        }
        return requestTime(address, NTP_PORT, timeout, networkForResolv);
    }

发现时间服务器出错。

修改：  
\\frameworks\\base\\core\\res\\res\\values\\config.xml

<string translatable="false" name="config_ntpServer">time1.apple.com</string>

总结国内连接不上谷歌的SNTP服务器，[time.android.com][]，time.google.com都连接不上。  
安卓是1-4，  
[time1.google.com][]  
[time2.google.com][]  
[time3.google.com][]  
[time4.google.com][]

修改config\_ntpServer为苹果的时间服务器，[time1.apple.com][]，苹果服务器是1-7.
