Re: [ntp:questions] Regarding Leap second adjustments
vasanth, Configure a server with local clock driver. Download the NIST leapseconds file. Set the server time shortly before the leap. Synchronize the client to the server. Watch what happens.

And ntp will ONLY adjust leapsecond on June 30 or Dec 31 of the year when the leapsecond warning bit is set, so your experiment will only occur in 2 weeks time, and will then take 6 months till it can be tried again. The client does nothing with that information except set the leap second warning bit, and at 23:59:59 of Dec 31 will insert an extra second. >I am new to NTP please provide some pointers for understanding. doc.ntp.org >Thanks, >Vasanth ___ questions mailing list questions@lists.ntp.org https://lists.ntp.org/mailman/listinfo/questions

The protocol doesn't specify how the local clock is handled, only what gets sent downstream. > as ntp client. server should send a leap second adjustment notification to > client and I would like to record the steps the client takes with this > notification.

[ntp:questions] Regarding Leap second adjustments
Hello Hackers, I am doing research on leap second adjustments in NTP. I would like to simulate the scenario with two machines one acting as ntp server and other as ntp client. server should send a leap second adjustment notification to client and I would like to record the steps the client takes with this notification. Could any one please let me know where i can hard code in server to send the LS (leap second bit set) to send to client. I am new to NTP please provide some pointers for understanding. Thanks, Vasanth ___ questions mailing list questions@lists.ntp.org https://lists.ntp.org/mailman/listinfo/questions
