As far as I can tell from my abundant good looks and limited forensic's skills, PVR Stalker doesn't respect daylight savings time in Kodi 15.0 - 15.2. There is a way to download and edit the EPG file to correct for this, however, as I have demonstrated in another post.

The alternative is to upgrade to Kodi 16.1, where PVR Stalker client will sync times correctly.
