    The clock runs slow in this image!!!

    Has anyone noticed any problems with the clock and the 1.3 version?

    By this I mean its the same TIVO motherboard, HDDs as I was using before, cachecard NOTHING hardware has changed! Reformatted and installed.

    Before with the old 1.0, I had cron set the clock 7 days a week at midnight.

    But during the day and night (furthest away from the time being set) recordings were spot on time. True I never checked the accuracy of the clock, but surely within 15 seconds per 24 hours my guess...

    Now this version my recordings are starting late, same shows!!! and I mean late by over a minute and more!

    I found the clock is now running slow, to the degree of approximately 15 seconds every 30 minutes!!! If I set the clock fixtivotime or fixtime.cron and type date, the clock matches my GPS time. I check it in 30 mins and its 15 seconds out!!!

    I have cron now setting the clock every hour, but surely something is a miss.

    Everything else is perfect, just the clock runs slow.

    Can the clock speed be adjusted anywhere?

    Thanks!

    CacheCard???

    Sorry no solution for you but there is a thread on the mailing list which could be related:

    http://minnie.tuhs.org/pipermail/ozt...il/012351.html

    Peter has two TiVo's losing time - around the same amount too. I understand that both of his run CacheCards (like yours). Could it be ... ?

    Craig Curtin theorised that Peter's problem could be a software issue in this post:

    Perhaps see how it goes without the CacheCard drivers?

    David,

    Thanks a lot for your help I will have a play around and see. Failing that it is something easily fixed, how often could I safely set cron updating the clock?

    I run my own NTP server on the network so it wont overload my server, but I dont want to overload tivo.

    I will post the time info on cachecard support also seeing if its a bug.

    Thanks!

    Got me there

    Hi.

    Frequent NTP updates on a TiVo are outside my experience I'm afraid. Anyone else???

    Even so I'd be surprised if your half hourly updates would overload it.

    I'm running the 1.3 image and have a CacheCard on the way. Hence I'm very interested to hear how you go.

    Cheers, Dave.

    I'm about to fire up my computer and connect via ppp to the TiVo, so as soon as I have an answer, I'll post it.

    Edit:
    telnet into tivo and edit crontab. This can be done in this way:
    Code:
    telnet 192.168.1.51
    rw
    cd /hack/etc
    vi crontab
    G
    i
    59 23 * * * /bin/ntpdate server.ip.address.here
    ESC ESC
    :wq
    sync
    ro
    For all those above, rw makes the file system read/write, using vi, "G" (capital G) makes it go to the last line. "i" (lower case i) is insert.

    59 23 * * * /bin/ntpdate server.ip.address.here
    59 minutes, 23 hours past ie. 11:59pm, execute ntpdate with the variable server ip address. I say server IP address because tivo cannot do dns/WINS lookups by default

    ESC ESC (press escape twice), :wq (colon, lower case "w", lower case "q") it will show on screen. This means "Write and Quit".

    sync - Write changes to disk just in case it writes them later and we reboot before then.

    ro - Set the file system back to "Read Only"

    If you know how to use "joe" to make the adjustments, go ahead. just remove the commands like "G" and "i" and ":wq" and such.

    tenty,

    Hmmm since I run my own NTP server, I did not think about using ntpdate

    Question.... If I update hourly say like:

    05 * * * * ntpdate 192.168.0.1

    Does this mean I can get rid of fixtime.cron completely as my Windows 2003 Server accounts for daylight savings If I check at 05, the server will report the new time (DST or no DST)?

    It executes so much faster than fixtime.cron, even though fixtime is looking at the same server....
