EPG time wrong

Thoie

I have a Philips TV that I'm picking up the DTT trials on.

Following some advice from this forum, when I set country to UK I have access to the EPG and MHEG. If I set the country to Ireland I don't.
The clock on the TV is showing the correct time (picking it up from the signal).

For the last while the EPG has been out by an hour. For example, it's currently 19:15. The RTE lineup for the next hour or so is

19:00 This sporting life
19:30 Eastenders
20:00 Fair City
20:30 Rachel Allen (does something with food)

If I turn on the EPG right now I see that the time is 19:15, but EPG is showing

19:00 Fair City
19:30 Rachel Allen


I can't go back an hour earlier (and see what's on all channels now on the guide). Is anyone else having this problem (in which case it's probably just a testing issue)?

I have had the exact same problem with the Sagem Picnic Box for a few months now and there is also no way of changing the time on the clock that I know of.

This has changed the clock on my tv also. I am not happy about that

As long as it's not just me then that's OK - it's probably because it's just a trial. I'm not sure how long it's been happening, but I wonder did they not change the {magical EPG time setting thingy} when the clocks changed? In which case it will all go right again at the end of October.

It will all be OK for launch, because that is when we go back to GMT. My picnic box has the time out by an hour since we went on summertime. Maybe Saorview sets will choose between GMT and summertime, and the UK spec just sends out 'time'. Can anyone check this. I have found no way of changing the time on the picnic box.

I have both Freeview and Saorview on the picnic box. While tuned into a Saorview channel, the epg is on GMT. While tuned into a Freeview channel, the epg switches to the correct time (summer time).

So it seems that either RTENL have not changed the time setting, or they are doing something differently which is not understood by the picnic box and it simply reverts to GMT.

STB

Country settings do diffrent things. The Picnic box is set for the UK. If it does not pick up the correct time etc being broadcast its because it chooses to do and receive certain things when a different country setting is chosen. Same way anything other than UK will switch off the MHEG5. Same way choosing UK will put the Irish DTT channels up in the 800s. This is stupid manufacturers not having up to date or limiting their country profiles. Its a simple firmware fix to just turn on the MHEG5 for Ireland when Ireland is chosen.

Same goes with the times..... infact you should have a choice to pick GMT+1 manually on any decent bit of hardware.

Little old Ireland, an afterthought.

I just checked and updated my EPG on my mediaportal based HTPC's. There was no issues before or after the EPG update. My HTPC's grab the DVB epg from the DVB source in much the same way as TV's or regular STB.

I'd agree with sesswhat's comments "either RTENL have not changed the time setting, or they are doing something differently which is not understood by the picnic box"

I don't think that RTENL are doing anything wrong as such. All EPG data broadcast in the EIT stream contains the timestamp in UTC (equivalent to GMT). There is a local time offset descriptor broadcast also. This is flagged as IRL and is set correctly to UTC +1 hour. The next change date is set as 31/10/2010 and the offset for then is set as UTC +0.
The issue is probably that the Picnic box (and others) are looking for the GBR time offset descriptor and because they can't find it in the RTENL data stream are setting their clock to UTC.
The satellite EPG from Astra contains both the IRL and GBR time offsets (which are of course the same), which overcomes the issue of different country settings in STBs or TVs with integrated satellite tuners. I can't check what data is in the Freeview stream as I can't receive it.

See my previous post. The EPG times are always set to UTC. The box either adjusts to summertime by looking at the country time offset in the data stream or has a manual summertime options (like on my Mvision combo box).

It's actually out by an hour and 2 minutes or so.

The time on DTT from RTE has been drifting fast relative to the time from satellite and ATT over the last few months.

If you have a combo receiver you can see this if you flick between channels. It's messy, as if you're watching RTE, and have a recording scheduled on satellite, it starts early and finishes early, and vice versa.

The time on RTENL DTT is fast by about a minute and 50 seconds. The additional hour you speak of is because your STB is not correctly picking up the IRL local time offset.

That said, 1 minute and 50 seconds is some error for local programming - makes the EPG undependable for reliable recording if the STB is setting its time from the DTT clock.
