Android獲取時間戳

按照時間順利排列是最多見的展現順利，計算當前時間與發佈時間差值，理所的

public static String getPublishTime(long publishTimeL) {
    String publishTime;
    long timeMillis = System.currentTimeMillis() - publishTimeL;
    long second = timeMillis / 1000;//秒
    if (second < 60) {
        publishTime = second + "秒";
    } else {
        long minute = second / 60;
        if (minute < 60) {
            publishTime = minute + "分鐘";
        } else {
            long hour = minute / 60;
            if (hour < 24) {
                publishTime = hour + "小時";
            } else {
                long day = hour / 24;
                publishTime = day + "天前";
            }
        }
    }
    return publishTime;
}

以上代碼看似沒有毛病，運行結果，是不對的，很顯然偏差很大，查看代碼pubishTime沒有問題，顯然獲取當前時間戳有問題，發佈的時間戳是10位數，獲取到的當前時間戳是13位，修改

long timeMillis = System.currentTimeMillis() - publishTimeL * 1000;

Docroot is: /usr/local/var/www

The default port has been set in /usr/local/etc/nginx/nginx.conf to 8080 so that
nginx can run without sudo.

nginx will load all files in /usr/local/etc/nginx/servers/.

To have launchd start nginx now and restart at login:
  brew services start nginx
Or, if you don't want/need a background service you can just run:
  nginx

==> Caveats
A CA file has been bootstrapped using certificates from the SystemRoots
keychain. To add additional certificates (e.g. the certificates added in
the System keychain), place .pem files in
  /usr/local/etc/openssl/certs

and run
  /usr/local/opt/openssl/bin/c_rehash

This formula is keg-only, which means it was not symlinked into /usr/local,
because Apple has deprecated use of OpenSSL in favor of its own TLS and crypto libraries.

If you need to have this software first in your PATH run:
  echo 'export PATH="/usr/local/opt/openssl/bin:$PATH"' >> ~/.bash_profile

For compilers to find this software you may need to set:
    LDFLAGS:  -L/usr/local/opt/openssl/lib
    CPPFLAGS: -I/usr/local/opt/openssl/include
