XMLTV tvguide.co.uk shifted by one day
I am receiving Freesat via SAT-IP and am generally using the over-the-air EPG which works well. However, there are a few channels for which I don't get any data (e.g. E4+1 and More 4) so I tried to get the EPG for those via XMLTV (tvguide.co.uk). This works in that I receive EPG data, but the data is shifted by one day. The EPG shows for Tuesday what is actually running on Wednesday.
Does anyone know this issue or at least could someone point me in a direction where to look?
(I googled the issue and all I could find was about shifts by an hour due to different timezones. However, the timezone does not seem to be the issue as the times are correct.)
