    All of my OnePasses on various channels started recording about 2 minutes late last night, cutting off the beginning of shows. These were recordings at different times on different networks. This morning all is back to normal. Anybody else see this? This happened on a Roamio Pro.

    Thanks for the link to the other thread.

    My situation is strange. It says that my last connection was at 7:29am this morning. But all shows recorded overnight were off until a 6:30am recording. That one and all of the 7:00am recordings were back on track, which is before the service connection. Very strange.

    At a command prompt, you can see the clock drift on TiVo's servers with this command:

    w32tm /monitor /computers:sjr1.tivo.com,sjr2.tivo.com,sjr3.tivo.com,time3.apple.com

    There is very long thread with much more detail: Clock off in Roamio by 2 minutes

    Rather than forcing a service connection, you could just run the internet diagnostics under Network Troubleshooting. It only takes a minute and sets the clock.

    You know I see this from time to time. What I don’t get is why we see it. There really should not be drift of any kind really. So what is the permanent fix going to be if any? Come on TiVo you can do it right can’t you?

    I never see it. True, it might happen and then correct before I do a recording.

    Thank you again! I was unaware of that option but just used that method and saw how the clock was set during the process.

    Knowing the solution would not have helped for last night and early morning recordings as I did not see the issue until watching shows this morning. And the whole thing only lasted fewer than 24 hours. But it's good to know the solution for the future.

    I just checked the servers and sjr1 is off about 14 seconds.

    Wow. That's really cool. I've never used that program/external command before. Here's my output after I forced my Window machine to sync via the GUI.

    What we saw in the past is some of the NTP servers would drift up to a couple of minutes, so you had to monitor over time as over a couple of hours they would drift from a few seconds off to a few minutes off.

    I don't know if that is what is going on now but if you have a suspect server you can use the following to monitor continuously

    w32tm /stripchart /computer:sjr1.tivo.com

    w32tm /stripchart /dataonly /computer:sjr1.tivo.com

    Substitute sjr1 sjr2 sjr3 as appropriate.

    First command displays a text-based graphic that illustrates how much off the server is from your machine. The second displays just the offsets with no text-based graphic

    If it is the same problem as before, the offsets will just keep increasing over time until they reach a max and then reset to close to accurate time.

    Not everyone would see that problem because at least one of the other servers would have accurate time and in certain scenarios it was random which one your TiVo decided to use when the 3 didn't agree, so you could reconnect to mothership over and over and some would get less accurate time and some would get more accurate time.

    My recordings this morning started around 20 seconds too late.

    The post from cwerdna showed 14 milliseconds, not 14 seconds.

    That was packet transit time reference. The offset on sjr1 was 8.9seconds from a just synced local clock.

    My bad, but 8.9 seconds still doesn't mean 2 minutes. Something else has to be going on here.

    So I blacklisted sjr1, sjr2 and sjr3 on my router and was still able to do a successful service connection. I believe there should have been an error. Maybe TiVo is still using some other time servers.

    I'm not the best source for help since I have never had a time problem.

    Joe,

    Is this relevant anymore (TiVo's ntp servers)? I thought they finally switched to using some of the standard Internet ntp servers.

    This post shows them using the NIST ntp servers.

    Clock off in Roamio by 2 minutes
