WDJT 58 PSIP data off by a full day

I noticed that 58 and its subchannels all have the PSIP time off by a full day.  49-1 has the same issue.  I would guess that 41-1 does too, but I don't feel like doing a rescan just to find out.  (I skip it, since it's on 58-2 anyway.)  Verified that, as of 11:00 tonight 5/31, WDJT et al showed time and date of 11:00 5/30.

DanDyer, if you still read the forum, could you please look into this?  Add perhaps check to verify that the TVGOS equipment is working properly as well?

Here's the reason I ask -- my DTVPal DVR has been in a fit for about a week, with the clock jumping all over the place and missing recordings.  When the time is off, it messes things up to the point that just watching TV becomes an exercise in futility.  

My DVR gets both PSIP and TVGOS.  I can see from other PSIP equipment that the ch58  time is off by a day, but have no way to know if the TVGOS data is coming through properly.

Thanks!

Will,

What type/model DVR is this?  Cable, Dish, OTA?  Sounds like you need a new box.

The DTVPal DVR is an OTA digital HD/SD DVR. He doesn't necessarily need a new box.

The problem with Ch. 58's PSIP station time being 24 hours (or some other amount) off has occurred before and corrupts scheduled recordings from triggering on time because this device can use local CBS PSIP station time for it's global time. This device can also use a CBS broadcast TVGOS based program guide.

Incorrect PSIP clock time also makes the entire PSIP based program guide incorrect, as well as adversely affecting any brand digital tuner's PSIP guide data.

I just email them and it gets fixed soon after.

Thanks.  I left a voicemail for Dan Dyer at 58 engineering yesterday, but haven't seen it fixed yet.  I'll shoot an email to them too.

The PSIP time and date was correct this morning at 10:30 AM on my DTVPal CECB.

If the time is still incorrect on your unit, you may need to do an unplug reset or factory reset.
Do you have F206 or F207 firmware that lets you set manual clock time?

I'm at work, so couldn't check the CBS PSIP time today, or the time on my DVR.  Last night CBS PSIP was still off by a day.  Glad to hear that it's correct now.

I have F207 for the firmware.  It has the ability to turn off TVGOS for the guide display, but even with that turned off, it will not allow a manual clock setting.  It still says "time automtically acquired by TVGOS" or something like that.  The clock seems to drift regardless of whether TVGOS is enabled or not; there is some speculation on avsforums that the clock will set based on PSIP at times (which makes no sense!).

I'll check status tonight.

PSIP time was corrected by 8:30am on Monday morning.  We know of the problem and have been trying to track it for several weeks.  We think we finally know what is causing the start of the problem, yet the computer should still not shift by an entire day.  We put correcting software on yesterday, and had the cause happen last night, but the time did not change.  We'll know more in a week.

Thanks for updating us!  It really is appreciated.

My DTVpal DVR must be a weird little beast, as its time jumped 24hrs again last night, even though PSIP did not.  (I verified correct PSIP w/ a CECB, side by side with the DVR which was 24 hrs off.  The DVR went back to the correct time 5 or so minutes later.)  Is the "cause" you mentioned perhaps affecting the TVGOS data/time that is sent out, even though PSIP time is not affected?  I'm grasping at straws trying to figure out what's happening with my shifting clock.

Well, here is what I know.  First, our PSIP computer, was losing it's internet connection and for some reason, it would force itself back 24 hours.  We've been applying different patches (Windows of course) to rectify the problem, but since it's happening at most once a week, it takes time to figure out if the patch works.  We'll know more about it in probably a week.  The PSIP computer controls the PSIP and time for 58.x and 49.x.  
As for TVGOS, yes, we are broadcasting that product on the 58.x streams.  Originally, this was supposed to be for digital receivers, but as of Januray, TVGOS has tried several times to add another data stream for analog receivers.  Whenever that analog stream was added (encoded as a digital stream), it would knock our audio off to several OTA viewers.
After about 5 months of troubleshooting, it was found that this is a nationwide problem with Panasonic DTVs built between 2 and 3 years ago of the TH series.  Somehow those DTVs were interpreting the additional data stream as another audio stream, and therefore just knocking all audio out.  The answer to solve the problem is to hit the SAP button twice on the DTV, and the problem corrects itself.
Your DTVPal should be looking for the digital TVGOS in PIDS 111H, and 112H, and the analog VBI TVGOS in PID 120H.  You may need to do a rescan, but I also know that you can tell your unit to select which streams to look for an use.  TVGOS says to give their customer service a call if you continue to have problems.

Thanks again Dan.  Can you tell if your PSIP problem cause (losing internet) happened again tonight?  At about 9:00, the PSIP data was correct, but the TVGOS time on the DTVpal DVR was off (slow) by 24 hrs. 10 minutes or so.  Seems the software patch worked for the PSIP time, but my (uneducated) guess is that it still affects whatever TVGOS time data my DVR is using.  The PSIP/TVGOS issues and timing seem coincedent.  

I have now set up a picture-in-picture from 2 sources that allows me to see both PSIP time as reported by a CECB and the DTVpal DVR simultaneously.  The disparity lasted from roughly 9:00 to 9:30.

Will,

I saw your post on AVS.  I have the DVR Pal and the time has been jumping around a bit last week (Memorial day weekend), but I haven't noticed any sort of pattern.  It apprear to be on track last night.  Im in Oak Creek.

So, is Ch. 58 actually sending out the analog TVGOS signal?

My DTVPal & Panasonic E85 would get fits and starts of data now and then, but mostly not.  Are there any tricks to get this to work?
