Title: ntpclient.tcz (TESTING) Description: ntpclient -- a small NTP client for unix-alike computers Version: 2007_365 Author: Larry Doolittle Original-site: http://doolittle.icarus.com/ntpclient/ Copying-policy: GNU General Public License Version 2 Size: 12.0K Extension_by: vitex Tags: ntpclient -- small NTP client unix-alike computers Comments: From http://doolittle.icarus.com/ntpclient/: ntpclient is an NTP (RFC-1305) client for unix-alike computers. Its functionality is a small subset of xntpd, but IMHO performs better (or at least has the potential to function better) within that limited scope. Since it is much smaller than xntpd, it is also more relevant for embedded computers. See http://doolittle.icarus.com/ntpclient/README and http://doolittle.icarus.com/ntpclient/HOWTO for more informtion. ----------------------------------------------------- This extension was built from http://doolittle.icarus.com/ntpclient/ntpclient_2007_365.tar.gz using CFLAGS='-march=i486 -mtune=i686 -Os -pipe'. The adjtimex command that is normally supplied with ntpclient is part of busybox. While this extension can be used as a daemon to adjust the system clock, Chrony is much easier to use. This extension is useful if you want to independently verify how well Chrony is working or if you want to set the sytem clock immediately using NTP time. Examples: $ ntpclient -c 1 -h pool.ntp.org day second elapsed stall skew dispersion freq 40179 64730.007 52736.0 16.7 -8557.8 57006.8 3254000 The fifth column (skew) gives the approximate offset in microseconds between the system clock and the specified NTP server. $ ntpclient -c 10 -i 60 -h pool.ntp.org This command will check the time every 60 seconds for 10 minutes. $ sudo ntpclient -s -c 1 -h pool.ntp.org This command sets the system clock based on the time returned from the specified NTP server. Running such a command as a cron job is a simple way to keep the system clock reasonably accurate, although time may be stepped backward. ----------------------------------------------------- Change-log: ---------- Current: 2010/01/03 First version
