Product Overview

Chrony

Description: Chrony is a versatile implementation of the Network Time Protocol (NTP). It can synchronize the system clock with NTP servers, reference clocks, and manual input using wristwatch. It is designed to deliver accurate and secure time even in unstable network conditions.

Network Time Protocol daemon

Description: The Network Time Protocol daemon (ntpd) is a program that synchronizes computer clocks over a network. It works by coordinating clocks across a variety of servers and clients using the Network Time Protocol to ensure accurate timekeeping.
