daylight savings time...

[daveid]

it seems that at least zap2it's listings get screwed up during the transitions for daylight savings time. i was wondering if anyone else noticed this to be an ongoing issue and/or had any advice as to how to workaround this.. i remember previously having to empty my epg and reload it completely to fill the gaps, but since it is the opposite transition this time, i have multiple shows in the same time slots, and things are a bit screwy.
any advice?

I'd personally try the empty/reload tactic again.

I find the best way to do a complete cleanout is to use the command line 'gbpvr -onlyemptyepg' then start GB-PVR and go to the System plugin and use the 'Update EPG' option. For some reason this seems to be better at performing a complete reload than using the -onlyupdateepg command.

Cheers,
Brian

The zap2it times are all supplied in UTC time, and should be fine before and after the transition time, assuming you've got your PC set to the correct timezone and set to automatically apply daylight savings.

This stuff hasnt changed in the last couple of years, and we've successfully made it through the last few daylight savings transitions, without the users having to do anything.

my computer is set to the right time zone, and to automatically adjust for daylights savings, but my tv guide is pretty weird tonight.. a lot of overlapping shows, and even two in the same exact time slot. i am attaching an image, the first circled saturday night live, there are actually two in that slot. and the other ones are obvious from looking at them. monday i will empty/reload my epg, as i do recall the last transition i had issues as well with blank hour long slots in the guide. i was just wondering if i was alone, i guess so...

I am puzzled at what happened with the times on my setup. I tried to install GBPVR09813.msi to replace an older version that I have been using successfully for quite a long time. After installation I noticed that the listings are off by one hour. I spent a long time trying to figure out what happened.

I checked all the settings on my pc to be sure I was set in the right time zone and to automatically apply daylight savings. I cleaned out EPG and reloaded. Since I have 3 Hauppauge PVR 150MCE boards I cleaned and reloaded all 3 just to be sure I didn't miss something. The settings were still one hour off. I went to Zap2it web site and deleted and reconfigured my settings. No success.

After a few hours of constant uninstalling, reinstallingand reconfiguring, I checked my other computer which has been successfully running GBPVR09813 for a few weeks. Lo and behold, its schedule is now one hour off. I have made no changes to this machine. It was correct and recording fine as of 8:30am today. It automatically updated EPG after finishing the last recording this morning.

This tells me that my installation was not at fault. It has to be the EPG data that was downloaded today. Will everything be correct tomorrow after the new time takes effect? Or will it continue to be off by one hour?

I am with daveid... Can anyone offer any advice or help?

My programming seems to have gotten scragged too. I just checked, and the PC did the time transition properly. And Zap2It seems to be correct (at least it is now), but the EPG data under gbpvr is all an hour early.

Maybe we need a new feature, that will automaticly trigger a complete EPG reload when we switch times?

Yeah mine were screwed up too. Everything was an hour early the night before, but after daylight savings time (today) everything seems fine.

We shouldnt have to - we never had to in the past.

Its not something affecting all US users or we'd see a whole heap of posts on this topic.

When inserting the EPG listings, GB-PVR just asks Windows to convert each of the UTC dates supplied by zap2it into a local date/time, which GB-PVR then stores in the database. For each of these dates, Windows uses the machine's timezone information, including daylight savings info, to calculate the correct local time. GB-PVR doesnt convert any of the dates itself.

Each time this daylight savings switch occurs, there seems to be some very small number of users that report this problem. I'm not sure exactly what is different about these users setups, but I wonder if it relates to the machine timezone being different from the users timezone? I'm not sure if that is even possible, but it is with regional settings like date/time display, currency display etc, where the machine setting can be different from the current user settings. The recording service which does the EPG update runs as a different user account, so picks up the machine settings, rather than the user settings.

i'm not sure why my machine displays this problem. but it is completely logical in how it happens. because at 2am it becomes 1am the shows normally scheduled to end at 2am are now starting at 1am and ending at 1am (not sure the time is exactly 2am, just a guess, the logic should still be clear). so a show that is supposed to end and start at the same time will show up like the saturday night live in my picture, where there were two in the exact same time slot.
it makes perfect sense for this to happen, as there are (in all actuality) two different 1ams, etc. because of the time moving back to 1 at 2 (or whatever the actual time is the transition takes place) and as far as those saturday night live shows go, i checked the local tv listings with titantv and there were three in a row scheduled, whereas gbpvr showed two in a row with two in the same slot, or three all together.
i don't really care too much about this, but i know i am not alone in the seemingly small number of users effected by this problem.
i know for a fact when i set up my pcs i set the machine timezone correctly as well as my user timezone. but i am also pretty certain that whatever the user selects as the timezone is the machines timezone.
another reason so few people might report this issue, is that sometimes (like with the snl) the epg appears normal, but there is the overlap. when we moved forward in spring, there seemed to be more people reporting the issue due to the gaps that were shown in their epgs. but i could be wrong there. it is also odd to me that i saw the issue in spring & now, and i have a completely different computer now..
oh well.. thanks for the input, and a wonderful program. maybe one day i'll figure this one out.. if not, oh well.. all that was screwed up for me was a snl for my gf, it recorded exactly one hour earlier than it should have, cutting off the first hour of the show..

MY listings from Zap2it are fine. My computer has correctly adjusted for daylight savings time for Eastern Standard Time (-0500). I use the program Automachron to keep the computer on time, correctly adjusted to take the time from Ottawa's NRC timeclock (the atomic clock in Colorado doesn't work east of Kingston, Ontario, I am told, at lieast in Canada).

However, I need to remember to adjust for shows that span 1am.-2am on the day of the change. Last April, I didn't get the show scheduled to be taped from 2.am-3.a.m because, moments before 2 a.m., the clock jumped forward and missed the show I wanted to tape (i.e. the 2a.m. start never occurred). This time, I quick-recorded a movie from 12:30-2:30 but because the time moved back at 2a.m., it stopped recording at 1:30 (i.e. when the clock jumped back, so did the computer's understanding of when the show would be over.

I consider it a minor problem because I really don't expect to have high taping needs at that time of the night!

p.s. I update the EPG at 5a.m. I imagine I would have had a bigger problem if I had choosen 2a.m. as the update time!
