No... completely not! If you are glad about the clocks on your own network with some unknown differentiation in the excellent time (and every other), then you're doing not ought to got end of associated NTP server. I set one informed my portable computer so as to synchronize multiple servers on a local network one of < one ms for a ergonomics test. Their place unit varied benefits, additionally, that area unit delineates below. Source for more about NTP Server.


Motivation:


Often, unadapted Ubuntu boxes use ntpdate (/usr/sbin/ntpdate) to synchronize with the clock sporadically with a few outside time server. This approach synchronizes the clock using a training course resolution (typically once a day).

Computer clocks region unit imperfect, and may drift in the (correct) time server during the afternoon. What is more, drift rates within the clocks debate |of various computers vary,from the suggestion of the day important variations could exist involving completely different domestically networked machines, which may interfere with jump operations (for example, ever have a makefile whine once moving ASCII text document one of completely different machines?) .

It is potential to run the NTP daemon on a machine on your network. It has multiple benefits: 1st, the NTP daemon step-by-step "learns" the drift rate of your native machine, and might correct to it during the day. Synchronization with higher level time servers happens several times on a daily basis, and tons of time servers that are entirely different may also be utilized to create the synchronization correct. The NTP daemon acts as associate correct time consumer, as close the excellent time as 25, maintaining your system clock.

In addition to keeping partner correct program clock, the NTP daemon enables a system on your system (if you would like) to function as connect NTP time server. Doing, therefore, can empower alternative machines in your own native system to synchronize together with your community area network time server in an exceedingly very quickly and proper manner, since network latency is diminished. During this method, the variants in clocks between computers in the network are unbroken as stripped-down as possible. Mac, connected even Windows boxes can synchronize with an NTP server, should you set one up.The place device choice, less personal, motivations for fitting a server as associate NTP server. To begin with, doing, therefore, could decrease the strain since alternative machines on your local area network can synchronize with a specified time server. Additionally, ntpdate has been deprecated in favour of victimization that the -q flag to get ntpd (which mimics its functionality). Although you are currently don't need to run ntpd within the backdrop, ntpdate can eventually get substituted with ntp you will have to become currently.
