The Yeller App recently published a blog post advising all sysadmins to use UTC. Here's an excerpt: Use UTC. Use UTC. Use UTC. Use UTC. Use UTC. Use UTC. Use UTC. Use UTC. Use UTC. Use UTC. Use UTC. Use UTC. Use UTC. Use UTC. Jokes aside, it's basically saying use only UTC means not bothering with Daylight Saving Time (DST), and the bugs that this brings ...

The problem you're having is that the network connection is most likely not yet set up when the sync is triggered. You should set up a scheduled task that runs at start-up, that waits until a network connection has been established. If this doesn't work, there are some older solutions to this problem, I can vouch for the top answer in that link as the batch ...

ntpdate utility connects to the NTP server ntp.jst.mfeed.ad.jp, get the current time and set the local time closely to it. It's like you correct the time on your watches according to the radio signal.

It will set the time using ntp.jst.mfeed.ad.jp as source NTP server. man ntpdate

First off pool.ntp.org is not a reccomended source for the Windows Time Service. See here: Active Directory Time Synchronisation - Time-Service Event ID 50 I am confused by your comment that this one server is off, but all the other ones are accurate, but you are using pool.ntp.org. In an Active Directory environment, the PDCe is the "root" time server ...

After some debugging and Aaron's help, I've found the problem. The ISC DHCP client fetches ntp servers information by default in Debian. Debian's ntpd init script makes it use that info, by extending /etc/ntp.conf with it. The resulting file is made available at /var/lib/ntp/ntp.conf.dhcp. The solution is, of course, properly configuring DHCP not to ...

The following web page appears to describe the basics of setting up an ntp client to use md5/symmetric key authentication. http://www.nist.gov/pml/div688/grp40/upload/-Instructions-for-using-the-NIST-authenticated-Network-Time-Protocol-NTP-server.pdf It is specific to a particular server's clients, but should be adaptable. I have not yet tested it.

I've had a similar issue. I think my time was about 5 minutes out... I tried all the usual w32time commands / restarted services and it wouldn't adjust... No Joy!! What I did in the end was purposefully set the time to something obscure e.g. a few months ahead or behind re-ran the w32time commands and hey presto it came back within a good tolerance (a few ...

Am I a noticeable burden to the pool? I.e. does it make any noticeable difference to the pool if I'm hitting from 20 servers or from 2? Given that the pool is in constant need of servers for many years (see [1]) I would say that although 2 or 20 servers don't really make a difference you should always remember that you are not alone. So you ...

Recommended /etc/ntp.conf is like that ####### driftfile /etc/ntp.drift disable monitor server 0.pool.ntp.org server 1.pool.ntp.org server 2.pool.ntp.org # deny client access by default restrict -4 default ignore restrict -6 default ignore # allow access for localhost... restrict 127.0.0.1 restrict ...
