Operating Systems Linux Red Hat Best way to sync time on a Linux machine Post 302859407 by RHCE on Thursday 3rd of October 2013 04:38:59 AM

I guess there is some confusion, what I meant is that if the ntpd service is not running and we need to sync the clock once or at regular intervals, only then the ntpdate command would be helpful.

I hope, my query is clear now that the ntpdate command to be used only if the service ntpd service is not running.

Regards

SYNC(8) 						    BSD System Manager's Manual 						   SYNC(8)

NAME
sync -- force completion of pending disk writes (flush cache) SYNOPSIS
sync DESCRIPTION
The sync utility can be called to ensure that all disk writes have been completed before the processor is halted in a way not suitably done by reboot(8) or halt(8). Generally, it is preferable to use reboot(8) or halt(8) to shut down the system, as they may perform additional actions such as resynchronizing the hardware clock and flushing internal caches before performing a final sync. The sync utility utilizes the sync(2) function call. SEE ALSO
fsync(2), sync(2), syncer(4), halt(8), reboot(8) HISTORY
A sync utility appeared in Version 4 AT&T UNIX. BSD
