Mar 23, 2023 · The ntpd program is an operating system daemon that synchronizes the system clock to remote NTP time servers or local reference clocks. It is a complete implementation of NTP version 4 defined by RFC 5905, but also retains compatible with version 3 defined by RFC 1305 and versions 1 and 2, defined by RFC 1059 and RFC 1119, respectively.

The ntpd program is an operating system daemon which sets and maintains the system time of day in synchronism with Internet standard time servers.

It is a complete implementation of the Network Time Protocol (NTP) version 4, but retains compatibility with versions 1, 2, and 3 as defined by RFC 1059, RFC 1119, and RFC 1305, respectively. ntpd performs most computations in 64-bit floating point arithmetic and uses 64-bit fixed point operations only when necessary to preserve the ultimate pre...

In Linux systems, NTP is implemented by a daemon running in user space. The default NTP user space daemon in Red Hat Enterprise Linux 7 is chronyd. It must be disabled if you want to use the ntpd daemon. See Chapter 18, Configuring NTP Using the chrony Suite for information on chrony.

Jun 20, 2018 · 使用ntpd服务，要好于ntpdate加cron的组合。 因为，ntpdate同步时间，会造成时间的跳跃，对一些依赖时间的程序和服务会造成影响。 比如sleep，timer等。 而且，ntpd服务可以在修正时间的同时，修正cpu tick。 理想的做法为，在开机的时候，使用ntpdate强制同步时间，在其他时候使用ntpd服务来同步时间。

Network Time Protocol is the most common method to synchronize the software clock of a GNU/Linux system with internet time servers. It is designed to mitigate the effects of variable network latency and can usually maintain time to within tens of …

Jan 11, 2022 · NTPD uses NTP ( network time protocol ) to access a specified time server over the internet. Later, it will keep your system time synchronized without your further intervention.

man ntpd (8): The ntpd daemon synchronizes the local clock to one or more remote NTP servers or local timedelta sensors. ntpd can also act as an NTP server itself, redistributing the local time. It implements the Simple Network Time Protocol version 4, as described in.

OpenNTPD is a FREE, easy-to-use implementation of the Network Time Protocol. It provides the ability to sync the local clock to remote NTP servers and can act as NTP server itself, redistributing the local clock.

The ntpd program is an operating system daemon that synchronizes the system clock to remote NTP time servers or local reference clocks. It is a complete implementation of NTP version 4 defined by RFC-5905, but also retains compatible with version 3 defined by RFC-1305 and versions 1 and 2, defined by RFC-1059 and RFC-1119, respectively.
