Configure NTP Client.
[1] The settings of NTP Client on CentOS are mostly the same with Server’s settings, so refer to NTPd Settings or Chrony Settings. For different settings from Server’s one, Clients don’t need to receive time synchronization requests from other computers, so it does not need to set access permission.
[2] If you don’t use NTP service daemon but use a command to sync time at once, use ntpdate like follows.
[root@localhost ~]# yum -y install ntpdate
[root@localhost ~]# ntpdate server 2.vn.pool.ntp.org
24 Jan 11:35:15 ntpdate[5740]: adjust time server xxx.xxx.xxx.xxx offset 0.004626 sec
[root@localhost ~]# systemctl enable ntpdateConfigure NTP Client on Windows. This example is based on Windows 10 Pro.
[3] Open [Control Panel] – [Date and Time] and move to [internet Time] tab, then [Change settings] button.
[4] Input NTP server you’d like to sync on [Server] section and [Update now] button.
[5] It’s OK to sync time if successuful message is shown like follows.
The default setting of sync interval is 86400 sec (one day).
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\W32Time\
TimeProviders\NtpClient\SpecialPollInterval
