LPIC 1 - 062 - 108.1 (2/2) - Maintain System Time; NTP and Chrony Services
Time is important and all operating systems need to keep track of it, even when the computer is not connected to any power source is is turned off! This is done via a clock on the motherboard and syncing it with internet time servers.
In this section we will see the Network Time Protocol and will learn how the system uses it to contact NTP servers to keep its time accurate using commands like `ntpdate`, `ntpq` and services like `ntpd` and its newer implementation `chrony`.
00:00 - Network Time Protocol (NTP)
04:15 - ntpdate to set time using NTP
07:55 - NTPd service
10:09 - ntpq command
11:11 - Chrony service and chronyc in Linux
