Starting about two weeks ago, all the shows have been listed an hour early in the guide - though they are fine in the XML file before it is imported. I use XMLTV to get the EPG files, but I run it manually on a separate computer, and copy the EPG file over to my PVR when I need to update it (if I were to hook my PVR up to the school network to get internet access, I would have to change a number of setting to abide by their policies, and I'd rather not).

Around the time this first happened, I searched the forums to see if anyone had had something like that happen to them, with the times being an hour off. I found a few people who had, and set about trying the remedies people suggested to them. First, I emptied the EPG, deleted the capture sources, set the capture sources up again, and re-imported the EPG. That did not work. After that, I tried uninstalling GBPVR, and reinstalling (while I was at it, reinstalling to the latest version. I don't recall which release I had before, but it was only one or two behind, I think. It was from last September, anyway.) That did not work. I checked the clock settings in Windows (I am using Windows 98, by the way), and it seems to be correct. I tried playing around with whether Windows was set to automatically update for daylight savings time, and that also made no difference. I also tried offsetting the EPG when importing (after having cleared it, deleted the capture sources, and re-creating them) but it had no effect. That last one I find a little odd, since it apparently ignored the offset setting altogether there.

The time that GBPVR shows is correct, it is just that the listings are an hour earlier than they should be, so I suspect the problem must be when I import the listings. I have XMLTV configured to get the times in UTC. There was one post I read that mentioned an XML cleaner that would switch UTC to GMT, but I didn't think that it would be necessary since it worked fine with UTC before, and I could find no mention of UTC vs GMT in the wiki.

The only thing left I can think of to check is the BIOS clock, though I thought that GBPVR converts times based on the Windows clock, so that shouldn't make any difference. Since this error started occurring for me, the only way I have been able to get correct listings is to edit the gbpvr.mdb file to manually shift the times back by an hour (though that has been an educational experience in itself, examining the different tables in there). If anyone can think of something else I should check the settings on, I would appreciate it. Thank you.

Which timezone are you in? and which country?

Can you post an example listing from your XMLTV file so I can see the date format?

What XMLTV grabber are you using?

GB-PVR doesnt work on Windows 98, so you must have that wrong?

Hi sub, I had the same problem a while ago in a different thread and CleanXMLTV fixed it for me. This started a week before the time change, I havent stopped using CleanXMLTV to see if it still has the problem.
Someone who's trying my incremental xmltv download utility is reporting the same problem, but they haven’t replied about the cleanxmltv fix.

Which timezone are you in? and which country?
(GMT-06:00) Central Time (US & Canada)

Can you post an example listing from your XMLTV file so I can see the date format?
I've attached a zip with tomorrow’s xmltv data.

What XMLTV grabber are you using?
tv_grab_na_dd from the link below.

I think this is because there was no support for the "UTC" timezone specified in your XMLTV files. The actual timezone tags that come after the date time arnt well specified by the XMLTV, so you get all sorts of grabbers doing it different ways. I added support for everyway that I was aware of early in 2004.

At the time this was implemented, zap2it didnt exist, and all USA based users used XMLTV. The USA XMLTV grabbers produced files with date times using the CST, PST, MST & EST timezones. Grabbers for all other countries either produced local times, or offsets relative to GMT, or a couple of other european timezones (CET, WET).

Until today, I'd never seen one that used "UTC" for the timezone. I guess whoever wrote the newer zap2it XMLTV grabber decided to add "UTC" to make their life easy since that is the timezone used natively by the zap2it data.

Thanks for the explanation sub,
It was a bit puzzling (and a mild panic attack Smile ) when it first happened, but it isn’t a big deal at all. CleanXMLTV patches the files and I haven’t had any problems since then.

My mistake. I should have checked again before posting. It does use Windows 2000.

I tried CleanXMLTV and it does solve the problem. I just wonder why I hadn't had any problem with the time codes being in UTC up to that point. Thank you for your help.
