Apple macOS (OS X)
- Buka System Preferences.
- Pilih panel "Tanggal & Waktu".
- Klik ikon gembok untuk membuat perubahan.
- Masukkan sandi Anda.
- Pilih "Tanggal & Waktu".
- Di kotak di samping "Setel tanggal dan waktu secara otomatis", masukkan
time.google.com.
Cisco IOS dan NX-OS
router# config t
Enter configuration commands, one per line. End with CNTL/Z.
router(config)# no ntp server
router(config)# ntp server time1.google.com
router(config)# ntp server time2.google.com
router(config)# ntp server time3.google.com
router(config)# ntp server time4.google.com
router(config)# copy running-config startup-config
Google Compute Engine
Meskipun Anda dapat menggunakan Google Public NTP dari Compute Engine, Anda akan mendapatkan performa yang lebih baik dari server cloud pribadi, yang menyajikan waktu yang sama menggunakan smear yang sama. Ikuti
petunjuk berikut.
Juniper Junos
NTP dikonfigurasi di tingkat hierarki [edit system ntp]:
system {
ntp {
server time1.google.com;
server time2.google.com;
server time3.google.com;
server time4.google.com;
}
}
Linux
ntpd atau chrony
- Edit
/etc/ntp.conf atau /etc/chrony/chrony.conf (bergantung pada layanan yang Anda gunakan) menggunakan editor teks favorit Anda.
- Hapus atau jadikan baris yang dimulai dengan
server sebagai komentar, untuk mencegah komputer Anda mencoba mencampur server yang sudah diolesi dan yang belum diolesi.
Tambahkan baris:
server time1.google.com iburst
server time2.google.com iburst
server time3.google.com iburst
server time4.google.com iburst
Mulai ulang daemon NTP/chrony menggunakan sudo service ntp reload atau sudo
service chrony force-reload.
systemd-timesyncd
- Edit
/etc/systemd/timesyncd.conf
Tetapkan konten blok [Time] ke:
[Time]
NTP=
FallbackNTP=time.google.com
Jika NTP= tidak dikomentari dan ditetapkan ke string kosong, daftar server NTP akan direset, termasuk penetapan per antarmuka. Hal ini mencegah
perpindahan yang tidak disengaja antara server waktu yang disamarkan dan tidak disamarkan.
Mengonfigurasi NTP Publik Google sebagai server penggantian akan menyebabkan server tersebut dipilih sebagai satu-satunya server NTP.
Mulai ulang systemd-timesyncd menggunakan systemctl restart
systemd-timesyncd.service sebagai pengguna dengan izin yang sesuai
Verifikasi bahwa sistem Anda menggunakan NTP Publik Google dengan timedatectl
show-timesync | grep ServerName. Jika berhasil dikonfigurasi, output
akan menampilkan: ServerName=time.google.com
Microsoft Windows
- Buka Panel Kontrol.
- Klik ikon "Tanggal dan Waktu".
- Pilih tab "Waktu Internet". (Opsi ini tidak akan tersedia jika PC Anda
adalah bagian dari domain. Dalam hal ini, komputer akan menyinkronkan waktu dengan pengontrol domain. Anda dapat mengonfigurasi pengontrol untuk menggunakan NTP Publik Google.)
- Klik tombol "Ubah setelan...".
- Centang kotak "Synchronize with an Internet time server".
- Di samping "Server:", masukkan
time.google.com.
