    I have series 4 premiere. the clock is about 10 seconds ahead of true time, and shows are thus being cut. how can i change the clock?

    thanks.

    What are you basing 'true time' off of? You can't change the clock, it is re-synched every time the Tivo connects.

    I would wager the 10 second differential you see is mostly due to a cable company lag. I just checked my TiVoHD's time against my automatic clock and they were within 1 second of each other. I record OTA and cable and always see a 5 to 20 second delay in my local channels coming over cable.

    You can't go by when a show starts or ends. Those are often off by a bit. Some networks are worse than others.

    Force a reconnect on the TiVo. While it runs, force a reconnect on your computer. Then test the time difference.

    how do I do that?

    the time is definitely off. even if it was a cable delay, i would be stuck always adding an extra minute, a pain.

    TIVO Central->Setting & Messages->Settings=>Network & Phone->Connect to the TiVo Service Now. It takes about 5 minutes.

    Windows 7->Change time & date settings...-->Internet Time->Change Settings->Update Now. Repeat "update now" until it works.

    Any changes after this are clock drift. I can't fix that.

    At least half the shows I watch either run late or are actually longer by a whole minute because of the (for me) outdated assumption that it will hook you into watching the next show. So I pad almost everything by a minute on the end and sometimes miss the first few seconds of show when there's a conflict.

    If your Tivo's clock is off by 10 minutes, that means it hasn't connected to the TiVo Service in quite awhile.

    You might want to be investigating why that is not happening.

    With my new Roamio I now pad all new season passes with a minute at the beginning and end. (Slowly adding that to most of my older season passes also.) I have not run into any conflicts yet. Six tuners is great!

    Some minor trivia with time, the most common time source people use now is GPS based however UTC and NIST (which is the "National Institute of Standards and Technology") have the official clocks, these clocks are I believe 16 seconds BEHIND the GPS clocks due to leap seconds.

    The earth is slowing down (I think somebody wanted to get off) so we need to adjust the clocks.

    Seconds not minutes.

    So which is correct?

    I thought I read that the NIST adjusted their clocks to compensate.

    So, UTC/NIST is the "true" time, but most GPS receivers automatically apply the UTC offset to GPS time so you're still seeing UTC on your GPS device.

    Yes and no, the GPS is applying your offset to UTC, however it is not accounting for leap seconds so the time displayed is not true UTC.

    See this page http://www.leapsecond.com/java/gpsclock.htm of course the clock shown is based upon your computer's clock but it does show the time differences between the different standards.

    Yep, they do that on purpose.
    Just to mess with us DVR users.

    I have had this same problem for years and years, the problem lies with your tv provider and i can say that with certainty after researching this like you wouldnt believe as it aggrivated the crap out of me.
    I also have a roamio and pad my stuff by a min at the end, exception is where there is two episodes back to back - example pawn stars, storage wars etc and it auto pads for me which is really cool.
    Sorry, theres not really a better way to resolve.

    Suddenly, just over the last week or less, I have noticed that my Tivo time is about 15 seconds behind. It hasn't had any adverse effect on anything, but it just seems odd. Maybe it will adjust itself, so I haven't worried about it.
