如何在android环境下获取internet当前时间

Answer 1

您可以使用以下程序从internet时间服务器获取时间

import java.io.IOException;

import org.apache.commons.net.time.TimeTCPClient;

public final class GetTime {

    public static final void main(String[] args) {
        try {
            TimeTCPClient client = new TimeTCPClient();
            try {
                // Set timeout of 60 seconds
                client.setDefaultTimeout(60000);
                // Connecting to time server
                // Other time servers can be found at : http://tf.nist.gov/tf-cgi/servers.cgi#
                // Make sure that your program NEVER queries a server more frequently than once every 4 seconds
                client.connect("time.nist.gov");
                System.out.println(client.getDate());
            } finally {
                client.disconnect();
            }
        } catch (IOException e) {
            e.printStackTrace();
        }
    }
}

1.您需要Apache Commons Net库才能工作。下载该库并添加到项目生成路径中。

（或者您也可以在这里使用修剪后的Apache Commons Net库:https://www-us.Apache.org/dist//Commons/Net/binaries/commons-net-3.6-bin.tar.gz，这足以从internet上获得时间）
