That is why I looked at the 5:30pm time as an option. At 5:30pm, the TVGOS time should be caught back up, but then the last download of the day goes from 5:31pm - 6:16pm, and after that the TVGOS time would be off by about 7 minutes (based on the WHIO data that was posted).
If you check your DVR time at 6:30 pm (before the update check at 6:55) is the clock correct? From what I remember other people saying, the one update reboot kept the clock correct for the next 24 hours. Just wondered if that is still true.
I've not been checking the clock accuracy nearly as often as I did when the problem was at its peak last year. However when I do look at it just prior to the auto update time, often it is off by a few minutes (but this error is less than it once was). For me the clock "fix" has been two things: doing auto updates, and setting recordings to always start early and/or end late. These are obviously band-aid fixes, but they are the only tools I have under my control. And they are not always sufficient. Every so often we still miss the very beginning of shows.
I do not necessarily believe that the clock is accurate for 24 hours after updating. I suspect that updates make it "good enough" for that evenings' recordings, but that it probably drifts continuously until the next update. Obviously I could track this more closely, but last year's events have me rather burned out on the matter!
One last thing.... Now that Channel Master is selling a new version of the DVR, I wonder if anyone has noticed whether its clock accuracy is improved? During last year's discussions about the clock, fingers were pointed at WUSA Ch 9, Rovi, TVGOS, etc., but also at possible problems with the operating system within the CM7000PAL. If the latter was truly so, maybe the new DVR is better in this regards?
