Network Time Protocol

Network Time Protocol Daemon

Also referred to as ntpd because it's a daemon.

There's a system called timesyncd (is it default now on Ubuntu?)~~, but~~ ntpd is more accurate so it's better to stick with that~~. I guess some people are complaining that it's not as maintained? But~~ if that'~~s the case~~, then ~~maintain it~~!

There's a new system called [https://wiki.archlinux.org/index.php/Systemd-timesyncd systemd-timesyncd] (Is it default now on Ubuntu?) ntpd is more accurate <ref>https://digitalbarbedwire.com/2015/05/16/debianubuntu-systemd-ntp-and-something-called-timesyncd/</ref> so it's better to stick with that if you have a system that is RTOS. Timesyncd is a client-only implementation and may be more suitable for most installations.

If you don't know what time it is, then how can you run [[cron]]?! Don't let your system get out of sync.
