如何获取局域网内其他机器上面的时间戳？

<?php
function net_time() {
    // set user and password
    shell_exec("net use \\\\192.168.0.2 \"password#\" /user:\"username\"");

    $output = array();
    $host = '192.168.0.2';
    $cmd = sprintf('net time \\\\%s', $host );

    $output = shell_exec( $cmd );
    $array = explode("\n\n", $output);
    $array = explode(" ", $array[0]);

    $array1 = explode("/", $array[2]);
    $array2 = explode(":", $array[3]);

    date_default_timezone_set("Etc/GMT-8");
    return mktime($array2[0], $array2[1], $array2[2], $array1[1], $array1[2], $array1[0]);
}
?>

完美解决了哈！
