Keberadaan Server Network Time Protocol sangatlah penting untuk melakukan sinkronisasi waktu perangkat server atau komputer anda. NTP digunakan untuk menyinkronkan ke Coordinated Universal Time (UTC) untuk itu diperlukan server publik yang terbuka untuk dilakukan proses sinkronisasi.
Inilah daftar NTP Server publik yang dapat digunakan
